Arylide Yellow
PY75
Pigment Description
Looses some lightfastness in tints, but otherwise decent lightfastness. This color is used in traffic paint, and Artiscreation mentions that it is possibly a good substitute for some chrome yellows (we would guess these are the warmer yellow-orange ones he is referencing). Rare as a single pigment oil, but found in a number of blends.
This color may metabolize to a potential carcinogen and could cause methemoglobinemia, see Monona Rossol's writing for more.
