Old Holland Indian Yellow-Brown Lake, transparent, duel-toned, PY:150
This permanent synthetic transparent pigment is the second half of the Indian Yellow hue.
This brown darker side also lightens into Yellow with a clear medium, just as the Indian Yellow golden/side does.
An important characteristic of Indian Yellow brown/side is the fact that it will make close to a neutral dark by mixing it with it's opposite color Ultramarine Blue Dark.
Which of the two Indian Yellows is on my palette most of the time? It depends on the scene, both sometimes, brown side is on all the time.
This color is excellent for mixing nature's Greens.
