This paint is unique to Rublev, no one else is making it.
Obscenely high chroma, this is the richest orange I have ever seen. It's tint power is very high, similar to a Phthalo in that respect.
Basically in masstone it is a glowing orange/red and it's tints are luminous, salmon pinks, very beautiful. Added to mixes it is going to bring light into them, particularly good for anything you are trying to render which is bathed in warm light.
It has a wonderful dense body, similar to the way Naples Yellow handles making it very pleasurable to use. Not surprisingly it is opaque and very opaque it is too.
When you have got used to the subtleties and delicacies of the many earth pigment paints Rublev make, then you use this, it is pure vibrant, glowing visual overload, I am utterly shocked, in a good way!
