This slightly granular blue-violet is an intense, vibrant color with medium staining properties. A brushstroke of concentrated Carbazole Violet onto dry paper moves the pigment from black-violet to clear purple, and can invent an iris petal with each stroke. Add Indigo to Carbazole Violet, along with Quinacridone Rose or Anthraquinoid Red. Blot, squeegee and incise damp passages to created veins, variegated passages and highlights
