Blue Pigments from Ancient to Modern: Comparison of Prussian Blue, Indigo, and Phthalo Blue

[@rossmcleod7983]

Pthalo blue haunts me and always has. It’s propensity to wander from studio to all points of the compass is nothing short of spectacular. Many thanks again for a wonderful tutorial, love your work.

Thanks for sharing!

Prussian blue is definitely one of my favourite pigments in oil paint. Although it can be hard to grind, I find the gritty texture useful, and love the way it diffuses light. One of my favourite replacements for black on my pallette as well. Thanks for such a lovely, informative video!

Thank you for the video. Do you ever sell Indigo paint already mixed with oil? I'm only finding the pigment.

[@RublevColours]

Not in oil paint, because the pigment is not very lightfast.

[@ZacharyZorbas]

@@RublevColours Ah okay, thank you.

[@sohelpervas4821]

I use rublive oil paint . Because rublive oil paints are free from additives .I want to store some oil paint . If I dont open the tube how long I can store the oil paint and if I open the tube how long it will be good for my usuing?

[@RublevColours]

It should last indefinitely if the tube is kept closed while not in use.

[@josephsnyder9186]

I heard that Prussian blue blackens over time is this true?

[@jahjahiscallin3237]

Given that there is risk of Prussian Blue fading if tinted with flake white and titanium white, do you think that the changes would be less noticeable if the tints were kept to a minimum. For instance, closer to middle values?

[@RublevColours]

The best practice is too apply Prussian blue as a glazing layer over another color, and not to mix it directly with white.

[@ayan4697]

@@RublevColours hm interesting. thank you for the advice. do you only apply prussian blue as a glaze once the color below is close to drying?

[@RublevColours]

@@ayan4697 Yes, only apply a glaze after the underlying paint is hard dry-not dry to the touch.

Thank-you for your video. I was wondering why there is not a lot of Cyan Blue paint? I remember buying gouache paint, Cyan, Magenta and Yellow, back 30 years ago. However. It seems that both Cyan and Magenta are not really offered much anymore. Is there a reason for this?
