Organic pigments - organic insoluble organic compounds of high coloring strength that are made in high-tech laboratories.

Organic pigments have wider range of bright colors, and many have excellent light and solvent resistance. They are divided into two groups:

  1. Azo pigments includes monoazo yellow and orange, di-azo, azo lake, benzimidazolone, bis-azo, naphthols, metal complexes.
  2. Non-azo pigments, heterocyclic and fused ring, include phthalocyanine, quinacridone, perylene and perinone, thioindigo, anthraquinone, dioxazine, isoindolinone and isoindoline, pyrrole, triarylcarbonium, quinophthalone.

I do not use organic pigments with biological origins (like alizarin, gamboge, rose madder, indigo, etc.) However, I use a few non-biological organic pigments (like quinacridones and phthalos). I usually avoid common lake and most phthalocyanine pigments. I love the intensity of Azo-pigments and use in small amounts some from these types:

  • magenta and red Quinacridones (I call them "quins" and use often the most lightfast versions) and  Perylenes,
  • yellow Hansas (I use sometimes in acrylic),
  • blue Indanthrones (I used in one series) and Phthalos (one shade of blue I reserve for a few special acrylic mixes; I phased out of green phthalocyanines).
