Old Holland Indian Yellow-Brown Lake Extra, Transparent, duel-toned.
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 PY:153 w/ Isoindolin, Org/side does.
The important characteristic of Indian Yellow brown/side is the fact that it will make a
good dark by mixing with it's opposite color, Ultramarine Blue Dark.
Which of the two Indian Yellows is on my palette most of the time? Indian Yellow brown/side.
This color is excellent mixing into Greens, Blues and Cyan's.
It is the 3rd color's darker half of the transparent primary triad.
The only 3 colors you need to paint anything in front of you.
The other two are magenta PR122 and cyan PB15.3
