A cold, deep crimson. In fact it is harder to find a cooler colour which isn't blue.
This is a poetic colour, it resonates with me and instantly generates some deep emotional responses, this would sit well in a Goya painting or a Francis Bacon.
If you mix some of this with Phthalo Green you will get such an intense black I suspect it is darker than most carbon based blacks. I find it interesting that you can have what is effectively a red colour which is so cold, the secret to this is revealed somewhat when a tint is made and the blue notes are easy to see.
Like all perylene pigments (first sold as pigments in 1957) it is transparent and non-toxic, it is extremely lightfast. As with Quinacridone Crimson it could be used as a cleaner replacement for Alizarin Crimson.
