[@nicopicco]

Hi Kevin, there is one thing that I was hoping you were going to touch on which I came across about 2 weeks ago. I see HSL as a circle of colors which (for me being bad with design and colors, I could not be an interior designer) could be used to your advantage when finding colors that go together. For example, complementary colors are opposite each other so, 180 degrees away from each other. The other is the triad color pairing, which would be about 120 degrees on each side of the color you are on ...then the square scheme is 90 degrees from each other. Just thought I would mention this because I really thought you were going to bring this up. For a non-color coordinated person like me, I find this very useful.

[@luchtaj]

Hey, this is awesome, as usual. Thanks for bringing the LCH up!

[@cmyk8964]

I prefer RGB because I’m a huge nerd and I have enough experience imagining R, G, and B values in my head as ratios. But when I’m designing a mockup on Inkscape, I use HSL when it’s more convenient, so that I can desaturate any color.

[@FlyAllTime2]

Very useful information that I could use yet didn't know about, well done Kevin.

[@codex4046]

I'm colorblind and I regularly use HEX colors to identify what kind of color something is. I prefer it over rgba. HSLA is something I just cant figure out how it works. I personally can identify colors by hex code quicker than by just looking at the color (looking at the color has about 40% chance I'm wrong, looking at hex that's only 5% or less). I guess I'm a wizard.

[@junehanabi1756]

The reason why hsl is loved is mainly in the manipulation of colors. In programming, you always want to use the most human workable data format. For example 60 * 60 to mean 1 hour instead of typing in 3600. It's just easier to understand and easy to modify. Even if you're good at reading hex, if asked to lighten by 5%, darken by 10%, or shift the hue by 15 degrees I would be impressed if you could do that instantly without first decompressing hex, converting to a readable format, making the changes, then re-converting back to hex

[@junehanabi1756]

Hsl basically means you, a css animation, or a script can easily and directly modify the hue, saturation, and lightness at anytime without fancy code. Creation of themes, color shifting, dynamic colors, or maintenance tweaks. Hsl is just phenomenal with this

[@adeleke5140]

@@junehanabi1756 that's exactly why I love and use it. It's so easy to create a consistent color scheme with it.

[@codex4046]

@@junehanabi1756 while that is true indeed seeing what color it actually is is way more difficult. Every IDE I have used so far has a one click conversion in color formats, so I use HSL for making small changes in lightness or saturation, but then will convert it back to HEX.

[@YaroLord]

you're one of the weird ones and definitely in the minority here with rgb you have to calculate the result of adding 3 values (r + g + b) with hsl you only have to calculate one: the hue - the other two are just how intense/bright the hue will be i literally cannot fathom a scenario where rgb is easier or simpler than hsl for web development

[@vintprox]

Glad you reminded me of how convenient HSL is. Not only it's enabling faster color inference without assistance from IDE, it's also more meaningful for anything that's going to extrapolate the color palette: fading long shadows, JavaScript customization, etc.

I dove into HSL a bit a few weeks ago during my work project. I mean hex is quite simple, easy to copy&paste and VSCode integration is so seemless. But you brought up an excellent point that crossed my mind as well a few weeks ago: the different shades are so much easier to make. I tend to be very precise when it comes to these things. Not too blue or not too yellow. But creating a simple :root map of the main colours is so easy and awesome to use. I'm still trying to push it through in our company (am not part of the dev team apart from UI/UX stuff). Great video Kevin and I will definitely read up the LCH stuff!

[@flaviomauri]

Oh perfect timing, just last week I scoured your channel in search of why you have been using HSL (from some time)! It’s undeniable that this colour space makes it easy to create shades, but I find the premise quite the specific scenario. What I mean is that I don’t think we should create palettes in the editor; it’s, I dunno… too abstract? Arbitrary? Ok when prototyping, but when working on a full blown project I would expect/imagine that a design has been done outside the code editor, the palette has already been set, we should have a style guide and in HTML we are just creating components from the library… so in a proper pipeline I would say that the problem of understanding the colour code is irrelevant, the work has already been done, you are using what’s been provided, even as a solo freelancer. Do you/people work directly in editor? This reminds me of the 37Signals post “why we skip photoshop” from many years ago, approach that I tried myself (and liked it)… but I think it’s really feasible when working on minimal interfaces; utilities, not brochure website. I wonder if at 37S/Basecamp they still skip the design phase (say mock-up). What seems most useful in HSL is the ability to easily manipulate colour dynamically.

[@AbWischBar]

HSL is definitely the way to go. But once more I would not have discovered it in CSS without your videos. We just always converted from HSL to RGB. That is just so wonderful with your channel 😀 There was an interesting article (need to find it again) explaining how colors in shadow have a strong saturation and low lightness, whereas colors in bright light have a low saturation and strong lightness. I found that using this principle makes for a very natural color scheme. But, hehe, for the years now, my team uses a self made luminosity calculator to align the colors in our palettes. So we play with HSL but compare the colors through that tool or let it adjust them. Will be cool once this is standard in browsers.

[@kevinmckraken]

I've used the HSL model for quite a while, because it was the easiest to understand/edit. My favorite part is in Sass, you don't need the percent signs, which makes things even better for me. It should be implied that the S and L are percent, so the requirement for the signs in regular CSS seems redundant.

[@aaronrothwell7615]

Yes I prefer it in Sass too, so you can set a brand colour, then have other colours auto adjust based on it, using the Sass functions

[@KrystianChynal]

Great tip on clicking the color picker to change color modes. BTW, any chance you could do a video on what extensions you use in Visual Studio Code and why.

[@BlurryBit]

It probably depends. I love 6/8 digit hexes because of simplicity too. For example, I would immediately know DD0000 would be almost Red. 00DD00 will be semi green, 0000DD will be semi blue (by semi I mean darker)... because it's rgb value. Each of the color has 2 hex digits assigned to them from 00 to FF. For 8 digit hashes, the last two are the alpha, and have the same scheme - 00 to FF. Atleast that's the way I learned. :) The same would apply for rgb/rgba as well.. the difference being that here the colors are from 0 to 255 (decimal) instead of 0 to FF (hexa decimal). More complicated colors can be difficult to figure out (for example let's say FFDD99) regardless of the scheme being used. It could be me only. :)

[@TristanSchaaf]

While technically correct, visually a lower brightness value might not always be what you want. So picking the colors, for design, should always be "hand picked". I don't know how LCH will resolve this. On note: The variable in hsl(var(--color), 50%); can be any color space. You can for example, define a color in hex, make it darker/lighter with HSL, and make it translucent with RGBA if you want to. Only ever needing to change one variable color.

[@autocosm]

Having the same actual brightness irrespective of a hue's natural luminance is great for contrast (should result in same ratio for same brightness) and data visualization (no spikes at yellow, cyan, magenta).

[@davi_singh]

Personal preference for color values is 1. RGBA -> making it lighter usually just tweaking the alpha value, darker is usually adding the same value for all 3 channels or sometimes just 1 channel 2. HEX -> i guess have just become comfortable with it, lighter usually means adding value to color on the opposite end of the color wheel, getting pretty decent at estimating it these days, darker same as RGB HSL is so alien to me, but will definitely give it a go now.

[@neubertdaniel]

Important info would be that if you still have to support IE you need to do some kind of polyfill. (Probably already done for the variables ^^)

[@junehanabi1756]

I've been using hsl for years and love it. I'm glad to see people talking about it. Almost no one seems to even know about it and I seem to have to explain why I don't just use hex. I know hex is short and sweet but geez this isn't 1998, there are other options out there. Why after decades is hex seemingly the only thing ever taught still.

[@alexisfy]

As a designer trying to learn to code. Yes, some good practices for good color usage in different devices suggest hsl and a a designer I suggest this for you too. It's easier to understand. There's a conference by the Lyft team that talks about colors consistency through devices

[@malcym3394]

Surely a colour is a colour is a colour. Getting into the depths of the various colour systems is interesting but, at the end of the day, do we really need to know, for example, the difference between additive & subtractive colour systems, or how to derive a colour, tint, shade by changing an element in the colour code? The most important factor in the PRACTICAL use of colour is the relationship of colours in a scheme. For that purpose, the standard colour wheel is the best way to determine which colours work well together. It's easy to determine colour chords, the work with tints & shades for a fully flexible, and easily understood/applied set of colours. How you choose to represent the chosen colours is secondary. We all consume colour via a screen, which ultimately means controlling the output of pixels, How the pixels are activated is pretty irrelevant. I could say that a given colour is called "gloxypantile". I just made that up, but that could be the start of my globally significant colour system. Red would be "antopiarelum" and green "hubbestrium". As long as I can convert those bits of gobbledygook int the RGB values used to set pixels, the underlying methodology is irrelevant. In other words, there's no need to understand the minutiae of colour systems - only to understand what colours work well together.

[@MM-vr8rj]

I mostly still use hex because it's nice and short. I don't really need to remember them because I use a vscode color palette extension in which I can save my color palette so I don't necessarily need to remember the exact values.

[@spicywasab]

The first one's probably a pretty light green blue-ish color (I know how to read hex colors since I'm 10 because of a video game's chat hidden feature) I don't really know for hex color codes with alpha valued, but assuming the alpha value is at the end (5E), it should be somewhere around 30%, since 16/5 ≈ 30%

"cant modify hex codes" what? #123 or #010203 is simple, r:1 g:2 b:3, but instead of writing it only between 0-9, you do 0-F, where A B C D E and F is 10 11 12 13 14 and 15, to make the colour darker, just lower the values proportionally, like change #09F to #07D etc

[@jameshskim]

Hi Kevin! I was wondering... Is it possible to colour a number based on its sign? Like: 1,2,3 are coloured black, but -3, -2, -1 are coloured red.

Something like with even and odd, just with positive and negative.

[@somnvm37]

I can kinda make hex myself. And read it. It is not that easy, but possible. I gussed to colour, it was "some kind of cyan, eith mostely green, and it is also not very light".

[@tommysmith5479]

HSL and the VS Code colour picker are both great. But I code (for my job) in the real world: that is to say that I get a colour pallette given to me by a designer. In that case hex is just fine. And because we use SASS, we just variablise (if such a word exists) each hex colour with a meaningful variable name. On a side note: I noticed that your website uses CSS variables - so can I assume that you don't use SASS?

[@kbcarte420]

I learned the vscode trick by mistake actually lol, game changer for sure. I used it most heavily for rgba to add alpha to colors designers give in hex. I'd still need to add the 'a' and a new parameter for the alpha but a game changer for sure to automajically convert between them all.

[@klesus]

You should be able to be fairly approximate with hex after realizing that hex is just rgb, but in hex. But other than that the only reason to choose one over the other I think is if there's supposed to be any dynamic shifts in color through javascript or something. Otherwise you'll just choose one visually through the tools in your IDE (and if you don't use an IDE that have tools for this then you should) or through other design tools like Photoshop, Kuler etc.

[@ch-yq5yn]

I've seen Hex used far more often then HSL. I'd recommend to use whatever the requirements of the designer are

[@KevinPowell]

[@vertigoz]

Why not hsb which is used on Photoshop?

[@Po4to]

The color's green value is the highest, with blue somewhat behind, but still way in the upper half, and the red is the lowest - which means it doesn't contribute much color, just makes the mixture of the other two colors a bit brighter. So it's minty green/lime green. The alpha is at 0.38 or so. Come on, hex isn't black magic. It's just RGB translated into hexadecimal. And it's the smallest in byte size - since you don't have to even type out the hex in duplets, a single-digit value will do unless you're super picky. So really, it's apples and #f80; rgb(255, 128,0); hsl(30deg,100%, 50%). Yes, it does get harder with tweaking saturation or lightness, but if you're into challenging tasks/useless exercises in futility, it's doable: lightness is increased by scaling the RGB values proportionately, and saturation can be toned down by proportionately levelling the differences in the RGB values. That LCH thing does look like an interesting development. Not going to change my religion, I guess, I will treat LCH as a preprocessor of sorts and convert it into hex for simplicity - but I do appreciate someone out there thinking about my poor, permanently sore, bloodshot eyes.

[@nomadshiba]

i think we can all agree, we are using the code editor or devtools to pick color

[@Dojan5]

You don't need to be much of a wizard, just understand hex. It's just base-16 with numbers going from 0 to F. The alpha value at 5 would make it the 6th number out of 16 so around 37-40% alpha. #36D6AB has some red, a lot of green, and a decent chunk of blue. Green and blue makes teal, and given that red isn't that low, and all the other values are decently high, I'd picture a decently bright teal.

[@flowerofash4439]

i feel like the saturation percentage is just how less grey smoke you want on your color

[@percurious]

Hey Kevin, thanks for your great videos! I recently stumbled uppon your channel and so far i realy enjoy your style, your perspective and your content overall! But: Aaargh! ;-) HEX is not a colormodel. HEX is RGB, just for nerds... If you understand RGB you can handle "HEX" with a bit of math :-) In the 6 char version, the first to chars represent R(ed) as a value between 0 and 255 (or R * 255) in hexadezimal encoding (0-9 mean what you are used to, a means 10 and f means 15; and you multiply the first digit by 16 and add the second. So A9=10*16+9=169~=0.66). The next two are G(reen), the last are B(lue). With 8 digits, the two additional ones are (op)A(city) ("alpha" realy). And three digits are just shorthand for 6: #f80 = #ff8800 ~= rgb(1.0, 0.5, 0.0) I like hexadecimal rgb much better then the css rgb() syntax for its conciseness. But i do love hsl() for its ease in tinkering just as you describe - and am looking foward to LCH! If youd be realy interested into color models, i' point you to brucelindbloom.com for a deep dive ;-) Thanks again for the video and sorry for the smartass-nerd-rant :-) Bests Simon

[@franki01mail]

I don't agree with using hsl on daily basis. In isolated coding environment it may work. But in the most cases, you work with 3rd parties - applications and people. Copy an RGB colour from/to Photoshop or copy an HSL colour - it's much easier to work with RBG colours in Photoshop. Send an HSL to a marketing agency that don't understand how HSL works and how to use it in Canva to create simple assets. With SASS/SCSS I don't even need to modify colours myself, I have saturate(), lighten(), darken() and they do everything for me. Or I can simply copy an RGB colour from other application, and I would say they all support RGB, unlike HSL (just a part). Plus I don't need to know what colour it is, because IDE tells me that.

[@6alonl]

I don’t think lch renders properly in safari at this moment. 0% lightness should give a black color but it’s not the case. Maybe this is how it’s supposed to be?

[@duck8dodgers]

Am I the only one who prefers Hex because it's actually telling you what the hardware is doing? I know RGB does this too, I just don't find it as intuitive, why force a decimal system onto values that are clearly hexadecimal? (I may be biased here, through my conlang geekery I was use to using non-decimal numerical systems long before I did coding of any type.) The HSL system is to far removed from what you are actually telling your computer screen to do. The Hue value in it to be a rather odd and arbitrary. Why split it in the middle of red? Why not go with violet at 360 so were are at least going from the longest to the shortest wavelengths of visible light?
