Color isn't what you think.

Most people think that "color" has nothing to do with luminosity (brightness,) but it does! The correct word for that is "chrominance!"
Here's the paper I'm citing:

In regards to computer monitors, CIELAB would be an absolute color space if a white point AND a white LEVEL were defined, but it's not, so it isn't.

I.e. an absolute coordinate system for color including luminance would be useful in those cases. Those are the kind of people who a lot of high-end consumer display equipment is targeted at, too.

[@TuckerDowns]

Yes! CIELAB is a relative color difference model. But it doesn't suck because we can measure two colors and convert them to the same white point and measure the percieved difference. That's how we can tell if a calibration is within noticeable tolerances. I don't like your calibration software though, because it is certifying that 400nits as being "good" when your target is 200nits. And yes to address the next point in your video LAB was design in the late 70s when monitors weren't bright and printing was still the dominate form of visual art. It used to be "standard" that monitors were around 100 nits but now we have issues where some people are mastering at 4,000 nits (candela per meter squared) but I have a laptop that can only display 500. 500nits is still HDR but it's not as HDR as 4,000 nits. That's why all the HDR formats include meta-data for end display tone mapping. Happy to chat more. This is litterally what I work on, every day, because I am the calibration / hdr / color science guy for a display manufacturer.

[@Quad5Ny]

It's DisplayCal as the GUI w/ArgyllCMS as the backend. And the window you're seeing is just for setting the display's whitepoint and backlight level. - You don't want to start with 1,000 cd/m2 and clip it in software to (ex:)120cd/m2, it's bad practice and you would end up with a ton of gradient banding.

[@TuckerDowns]

In any case, if your target white point is 200nits no software should have a green check mark at 400 nits. In response to your second question I'd say that actually that's exactly what you should do and that if you are using enough bit depth you will not have banding. (Using the PQ electro-optical transfer function, you only need 12 bit encoding but you need ... 26? for any linear space processing) I don't have anything to submit to you as proof, but I can say I've heard it directly from the horse's mouth (Dolby, Netflix) that they are grading at 4,000 nits for the master grade and then tone mapping to a smaller color volume for SDR distribution. I know that this is Dolby's preferred method for creating dolby cinema masters as well. Although sometimes the studios want to grade in SDR first. Keep in mind, dolby cinema is only 108nits display, but their preferred mastering workflow is to master on a Dolby Pulsar 4,000 nit monitor first and then tone map. I will agree with you though that you don't want to clip to 120 nits. It will create a very "blown out" look to the video. Instead, for tone mapping from 4,000 nits to 200 or something smaller you should use a soft clip. ITU BT Rec. 2390 had some information about this I think but I don't wantDolby Vision and HDR10+ HDR formats utilize dynamic scene by scene metadata to inform an end display / end playback software how to soft map to a smaller color volume. We are going to continue to see higher and higher brightness displays, especially as micro-led direct view displays come on the market in a few years. There will be a ton of variability in end display devices. For SDR content, those displays, if calibrated, can always show the content in SDR at 100 or 200 nits. But there will be content creators that want to take advantage of the increased display capability and for those creators this "how to I master for so many different brightnesses" problem will become worse. Another final bit of good news: I hope (and I think it will happen too) that the new ICtCp color space will start to replace YCbCr. ICtCp is a color difference space that, combined with PQ encoding, can accurately represent the full Rec. 2020 gamut from 0 to 10,000 nits without any noticeable contrast steps (banding) in 12 bits. Additionally, ICtCp separates chromaticity encoding and luminance much much more efficiently than YCbCr which means end device rendering can efficiently apply meta-data based tone mapping on only the luminance component of the signal without causing a chromaticity shift which can be seen when doing the same process on YCbCr. The ICtCp encoding is already supported by HDMI and SDI (and display port I think) so as far as signaling standards go, it's possible to adopt today. Not all equipment manufacturers have implemented support for ICtCp yet but I think adoption will steadily grow in the next few years. For cases where the mastering display had, say, a brightness of 500 nits but some end display has 1,500 nit display capability, with the metadata about mastering display brightness and color volume available, the end display system (renderer + display) should just display that content at 500nits. Actually interpolating a 500 nit mastered signal (or 120nit SDR master) up to a much higher brightness is where it is more likely that you will see very bad contrast steps. Especially if that content is mastered in 8 bits.

[@heikki4919]

What calibration software do you recommend? I have the X-rite i1Display Pro

[@Quad5Ny]

I think we turned KZbin into the avsforum

[@TuckerDowns]

​@@heikki4919 I have that display colorimeter at work and like it. All our desktop monitors are LG 32UD99 and I would recommend you use the manufacturer's LG True Color pro software. The true color pro software for LG monitors actually loads a calibration look up table onto the hardware of the monitor which can be a really big impact in calibration. The true color pro software works with the X-rite i1Display Pro For calibrating monitors that don't have manufacturer provided software, we've used several things. Currently I've been evaluating "basICColor 5" which can create an ICC display profile for the monitor that you can load into the graphics drivers. On MacOS this is very easy. From then on the OS drivers will send the "correct colors for the correct signal." A lot of programs and media formats, like JPG, allow you embed an ICC profile in the media itself. So for instance, if I create a picture and put an ICC profile for the rec.709 color space in the image, if you have done the above process for calibrating your monitor then the graphics driver + image preview software will compare the ICC profiles and still display the image in rec. 709 even if you have calibrated your display for DCI-P3 or some other color space. I will not say that I have comprehensively evaluated bassICColor 5 but I do like it so far and it does work well for creating display profiles on MacOS. I have not used it on a windows machine but I know that nvidia supports ICC profiles and basICColor creates ICC profiles so I assume the process should be relatively the same.

Taran you need to do a video on LTT about this stuff because when I looked into color spaces and all that garbage it was ridiculously confusing and this short 10 minute video explained the difference between chromaticity and color so well!

[@TheresaS179]

Dear Taran, Your observations are valid, except your sense that pigment is somehow independent of this effect, which it is not. Actually the same luminosity issues apply to pigment ("paint" as you referred to it), the only real difference is that with pigment, the ambient, or viewing illumination passes through the pigment twice. The ambient illumination strikes the surface and passes through the pigment once, then it reflects off of the paper or other material carrying the pigment, and passes through the pigment a second time before then reaching your eyes. The ambient light luminance, combined with the reflectivity of the backing material which the pigment is on, has an exactly comparable impact to the luminance of your monitor. And yes, it has a profound impact on color perception. When you really go a little crazy is when you realize that every person's retinas have profoundly different color sensitivity, dynamic range, etc. as well. There are significant perceptual differences between young and old, male and female, as well as individual to individual, and undoubtedly different ethnicities as well. It's all compromises, approximations, and useful fictions. But some standardization and means of comparison is better than nothing. There is a point of diminishing returns from getting too "wrapped around the axle" about all of this. Welcome to the "analog" real world. It may be less elegant logically than the digital abstractions we find so useful, but it has its advantages too. Cheers!

[@TuckerDowns]

Totally! I was going to add some comments above about how his pantone colors will change if he takes them into an art gallery, or a picnic, or a candle-lit dinner. Pantone does not standardize a color very well but instead standardizes a pigment recipe.

[@TacetTheTerror]

Add color blind to the mix for even more complexity! Then none of those reds are reds to some people.

[@MangoMotors]

But that's different because with color blindness the problem doesn't lie with the output of the color the problem exists within the input of colors into your eyes. Just because someone can't perceive something as red, doesn't mean that a color isn't red.

I have moderate red-green colorblindness. On a back-lit screen I can differentiate fine, in a room with bright lighting I can differentiate fine, on dreary overcast days and in evenings certain shades or red/green just look like blacks and greys. The bright ones are fine, its the subtle ones that are sometimes issues. Luminosity of the colors basically makes it a non-issue for my type of colorblindness.

[@RicoBrassers]

Well, I guess they are though. But they just don't perceive it as intended. The thing is - color is basicly a subjective thing for humans, you can't describe it to somebody with words, who can't see the color. So, if a colorblind person sees (our) gray instead of (our) red, it is still (their) red, if they've grown up learning that this color is red, without knowing that they are colorblind. Regarding the enchroma glasses: Imagine putting a red bucket infront of a person, who can't perceive red colors as we do (let's say they perceive it as gray), without telling them, that the bucket is red. Now they put on the enchroma glasses and actually perceive the red bucket as red - but since they've never perceived the actual color of red, they don't know what it is. They can guess that it should be red. But they won't know for sure, especially if you let them wear the enchroma glasses without telling them what they do. I think, it's aboslute fantastic, mind-boggling and mind-blowing at the same time. Colors are such a complex thing, even though they appear as such a basic and simple thing to us.

Luminance doesn't matter much for the human eye. It adapts to a wide range of luminance. What you WANT with the absolute color space will not be absolute. It will change depending on how well-lit the room is. Literally, the perception of the human eye of the colors will change depending on the background of the monitor. So color space that is absolute in regard of luminance is useless, Taran.

[@acanalesc]

For those who do 3D rendering it's even worse, because for us, color is actually the sum of light from different layers of a surface interacting with the lightsource and how it behaves depends, appart from the specularity and emission of the surface, it also depends of the Albedo (which we refer to as the Raw color, which by itself its way more complex than just a pantone). Color is a heckin big topic to talk about, and many people will argue how different what they know is and how true it actually is, and turns out, we are all right, it's all part of visible spectrum of light.... But if you don't want to sleep tonight, thing about how negatives work, and how does the light that we do not see affect them ;).

[@jakewhiteley1751]

In digital video production, you should be calibrating to Rec.709 and 100 nits. It's an industry standard for a reason. If you're mastering for HDR you should calibrate to 2020 and your luminance should be set to the luminance of the monitor. I think Dolby Vision requires at least 4k nits. Everyone who disagrees with me should unsub. Everyone who agrees with me should unsub as well.

[@TuckerDowns]

Dolby regularly grades media on 4k nit displays. And Dolby Cinema at a high end movie theatre is 108 nits. Both of these are HDR formats, in the cinema specifically because the black level is so low compared to normal ambient viewing conditions. However, in a research lab environment Dolby actually has displays capable of up to 20,000 nits brightness. With that display they determined that a display maximum brightness of 10,000 nits and a black level as low as possible (unfortunately the could not find a good lower bound) provided enough contrast to satisfy 90% of viewers which is why they designed PQ electro-optical transfer function to encode values between 0 and 10,000 nits in 12 bits.

[@smilebagsYT]

Great observation. Colour science talk about luminosity and chromaticity separately. The absolute luminosity isn't specified in colour spaces. LAB is used regardless of the source of the light. Standardising luminosity is sort of pointless in most cases, and in the cases where it is useful, it already exists. HDR standards specify colours (meaning an RGB triplet) with a white level of 1000 nits AND uses REC.2020, this means the white point (the chromaticity of pure white), the chromaticity of the RGB primaries (How saturated R, G, and B look) are standardised by REC.2020 and the absolute brightness of white is standardised as well. Problem is, most screens and software don't handle colour spaces correctly, especially when it comes to HDR standards and absolute luminosity. Chromaticity is hue and saturation (avoiding the word colour here). Luminosity is brightness. Colour spaces define standards for RGB to chromaticity mapping. Luminosity ususally isn't standardised but is in the various HDR specs. Also don't confuse reflectance from emission when it comes to comparing colours. Anything that reflects light can only ever (with a few exceptions such as flourescence) reflect less light than what hits them. If you shine a single wavelength of green light into a room (one pure wavelength, not, for example, green from a computer screen which contains a mix of wavelengths) then everything will either appear that same green, or black. Emissive light sources emit the same spectrum regardless of the ambient light. The most common way to specify colours for reflective materials like paints is to use a 'Standard Illuminant' like D65 (which is the same spectrum as seen in daylight) and see what the resulting spectrum is.

[@TaranVH]

Yeah, it gets more complex, but I'm really only worried about screens. Also, if 1000 nits is the standard, and my monitor only goes up to 500 nits... Is it like, faux HDR? Half HDR?

[@smilebagsYT]

@@TaranVH yep, pretty much. Or more like HDR with marketing and sales department stuffing with everything. If it is spec compliant, I believe when displaying HDR authored content in a supporting program, the white point will be correctly clipped, meaning the brightest whites of the source footage won't be reproduced but everything else will be reproduced accurately.

[@Quad5Ny]

@@TaranVH The display will roll-off or outright clip the values it cannot display.

[@erejnion]

@@TaranVH It gets worse even for screens. The screen will appear different to the human eye too depending on what it is surrounded with. The human perception of color is mostly dependent on DIFFERENCES between colors, so the humans easily compensate for the brightness if they see the same scene twice in different brightness. On the other hand, the human eye CANNOT easily compensate watching an ultra-bright monitor in a dark room. Or vice versa: watching a toned-down monitor in a bright room. That's why the peak 1000 nits brightness for HDR are a standard... for watching the monitor in daylight. That's all this standard says: you'll get the best HDR experience even if the environment is really bright. Good 400 nits HDR monitors will provide the same experience... if you have the room to be much darker. In a bright room the human eye fucks itself up and you can no longer discern small differences between two near-blacks, so you get a much lower effective contrast ratio for the monitor. In a dark room 1000 nits would be effing blinding.

[@TuckerDowns]

@@smilebagsYT There has been a lot of talk at various display conferences that I've been to about what brightness is HDR. One major manufacturer I heard from put it so well by saying "HDR means Higher Dynamic Range" and isn't defined by a maximum. I've explained it in a comment above but the goal right now is that media should have meta-data about the display it was mastered on. That way end displays and rendering software can correctly display media that was mastered at a different brightness than the attached display is capable of.

Pretty interesting video, but your biggest issue is that you’re using consumer computer monitors in the wrong environment. If you were actually working with color in a professional space you would need something like a Flanders scientific with the video signal coming out of a breakout box, the proper color space settings selected in resolve, in a dark room with the monitor backlit with the proper color temp, and it would need regular calibrating. You would also need to make sure to adjust your eyes every so often because your brain will automatically compensate and “correct” the image itself which is why the color on the display may look different than you perceive. Just because your monitor is HDR doesn’t mean it’s good enough for color.

[@totalnastoka]

Honestly, you should have known about this for years, this sounds like an undergrad who's just getting into color theory. That aside, wtf is with 400 and 200 nits you're using and why? I'm a high-end professional retoucher (you know, the type that work on beauty ads that get published in major publications) and it's standard practice to use 100-120 nits if you want the actual color (not chromaticity) to match. So just lower the brigthness on your monitors and you'll have no issues. The fact that other people will be viewing your videos on devices ranging from 50 to 500 nits doesn't matter, you don't calibrate for them. Most of them don't have calibrated monitors anyway, so they won't get to see what you intend them to see anyway. But if you want to be as close to standard as possible (as you should), you know your color space, now you also know which brightness to set your monitor to. P.S. monitor manufacturers can't show you the exact nits (as opposed to a 1-100 scale), because the meaning of that scale changes over time - becasue the backlighting slowly degrades. 72 brightness won't be the same as 72 brightness in 3 months. That's WHY you calibrate, geez! This really seems like a poorly informed rant, and if I were you, I'd probably read a bit more before ranting.

@@totalnastoka I did already know that. But I started to doubt it, because in so much of what I've been reading, the authors have been speaking about color as though it doesn't involve luminosity. Thus my incredible confusion, finally resolved by finding that one article.

[@CorerMaximus]

Been thinking about this for a few months now- I'm glad someone with a voice than can actually influence things (aka- Taran) is pointing this out publicly.

[@goolaguser3702]

Brilliant video. I actually knew about HSV color space and luminosity because computer graphics programming is my hobby. However, this gave me some new perspective. I think when computer color space systems are defined, the intended screen luminosity has to be defined along with the ambient light level on the background wall behind the monitor.

in before Tarans blows up

[@musa4539]

"not a single photon is bouncing off of a red color if you're in a cave" 0:22 False, you still emit photons, you just cannot see it. Yes, YOU emit photons as well! Gotta read up on electromagnetic radiation and how / why it happens. Don't forget other spectrums!

[@matthewwalburn2529]

No one has ever been so passionate about colors.

[@plocky401]

i've always thought of that, and someone finally made a vdeo about it

[@j.c.527]

sure, expensive professional monitors are calibrated, but what about a cheap tn panel with really bad contrast and color accuracy? what about low blue light monitors? no content creator will ever be able to control how ALL their viewers see their content, even if a standard color space existed

[@TaranVH]

Which is why it's all the more important to start with a properly calibrated monitor.

[@hecz0r]

i completely understand your ocd about this but i'd say the difference is usually unnoticeable between grading to a "standard" and to a non standard. if what you output looks fine at most luminosities then i'd say it's adequate

[@TaranVH]

No. If you color grade for HDR, and then watch it in SDR, it won't look good at all. So I hear.

[@hecz0r]

then assuming most people watch on SDR, grade on SDR

[@pedro_mab]

so you hear from people who are consuming the content or from people who create it? cause there's a big difference

[@gsora]

Ah yes, the kind of content I subscribed for: technical rants. Great video 👌

[@RprtBak]

I've literally been saying this for so many fucking years. How bright something is on your screens literally affects the "color" of it. Something at 1 brightness is going to have a drastically different "color" than at 100 brightness... But noooo. That makes too much fucking sense. But I didn't know about chromaticity, very helpful actually. Thank you kind sir.

[@vandalest]

It gets even more worse as also the room's lighting (bulbs, sun and computer blinking LED's) matter as that light is reflected off from LCD screens (in a minute way) and that changes the colours you see from the LCD screens. I have the ultimate Golden rule for video colour calibration that is also the cheapest solution: Buy the most average cheap LCD that is bought by the most average users (most popular in sales) and never calibrate it, keep the factory calibration. Now you can adjust the video colours how you like and the average user will see same colours on their cheap average screens.

[@ManuelRego]

the real life pro tip is always in the comments!

[@stevenexnihilo1338]

To think that this guy works for linus. Why it ought to be the other way around, don't you think?

[@Sum1Better]

Man you are a genius. I so hate changing my monitor with each game I’m playing. This is something I can rise up for. I’ve probably shared this to everything...twice

[@MattiaMari]

This is like the most informed rant I've ever listened to

[@evertchin]

CIELAB should really be ashamed of themselves for coming up with a "standard" that are subjective to so many variables.... now i dont feel so bad for picking a close enough "color" whenever i code a website. the reality is even the "standards" are vastly subjective.

[@TaranVH]

YEAH

[@erejnion]

The reality is that the human perception of color is even more subjective, and no standard has even come close to emulating it properly.

[@TuckerDowns]

Yeah. Web colors are terrible. HSL, Lab, and RGB. Google chrome at least tries to stuff all of those into rec. 709 so 0xFF0000 on a color managed monitor viewed in google chrome *should* be rec. 709 red but your milage may vary. I'd be curious if a lot of people did this test what they would come up with.

[@fits]

My favorite color is blue.

[@xX_DRKGORGNO_Xx]

You mean chromaticity?

[@jjpark98]

Well this is news to me. Thanks Taran for your contribution to my seemingly expanding but ever so dwindling knowledge. As always your channel is inspiring

[@Lukeade815]

youve stopped looking for answers and are instead looking for questions. perception is reality and perfection is unattainable

[@ragilmalik]

Colour (what you see) is a reflection by an object, reflecting the only wave it can't absorb. If what you see is red, then the material of the object pointed by the source of light can only absorb every wave but red. You're not wrong, but you need to address that your argument is not based on science

[@TaranVH]

What? That has nothing to do with what I'm talking about. And candela per meter squared is like... a scientific measurement.

[@GnosticOrthodoxChurch]

lol only peasants use hsl and chrominance to measure colour btw, my fave color is on a wavelength 432 nm

[@tbx1024]

Feels like with new HDR monitors becoming mainstream, that will become more and more needed. Thanks for sharing!

[@evieprpl]

god this stuff has been bothering me for weeks thx taran for finally explaining it

[@ATTACKofthe6STRINGS]

Taran, you're my spirit animal. This type of pedantic anger the inconsistencies of the world literally fuels certain aspects of my life. I edit my photos with a heavy reliance on check layers and reference points to get the kind of look i want. on of my recent photos looks too blue on my iphone, even though I edited the photo on a screen that I calibrated not long ago. I'm always trying to optimize the things I do, and this type of inconsistency bothers me to no end. I loved this video!

[@topbesttalent7099]

Taran Van Hemert your channel is great, thanks for the awesome video's your rock, channels like your gave me the inspiration to create my own channel to reach as many people around the world hope I can Grow and do what you do.Keep up the great Work....A+A+A+

[@robertonofrei384]

when the edibles kick in and you start to overthink about random shit

[@colinbtw8720]

Wow I actually learned something really neat, thanks Taran!

[@tomsdoe5445]

Congrstulations, you just finished high school and explained a basic idea as if it was a new nobel discovery.

[@kartiksharma2818]

I was once thinking bout this concept too. But boy you cleared it all.

[@DrakiniteOfficial]

Fascinating. I never would have guessed this

[@MsDesignDiva]

this is so helpful and it explains why I've never been able to get my second monitor to match my main computer, so ugh!

[@JGWalrus]

You did this at work. That's the best thing to me.

[@micahrodriguez7881]

I don't know how this ended up in my Watch Later Playlist but I'm glad it did

[@nadhifikbarwibowo2837]

I like this new format of TED Talk

[@castin5244]

"Hey man, nice car! Love the chromaticity!"

[@1337cyborg]

Thanks for all of your research into this.

[@peterdessev536]

Yes Taran! STANDARDIZE EVERYTHING!!!! you shall build a great nation.

[@M7MAD520]

I feel somewhat educated. Thank you, Taran.

[@DanielLearmouth]

Never thought I'd be learning something this early in the morning, but you know what? This is pretty damn intriguing.

[@ReadableLetters]

This was the most sensible rant I've ever heard from Taran.

[@harrytsang1501]

I don't know why but your professional frustration entertains me

[@ricardopieper11]

i've spent the last 3 hours looking into color space stuff due to this video (and some of taran's comments), thanks though, it's kinda interesting

[@valen8560]

very dramatic way of presentation, I like it
