Nickel Azo Yellow (PY150) is one half of the mix that makes up one of my favorite colors, Quinacridone Gold. Amongst the various Yellow Ochre options in the Daniel Smith Dot Cards, Nickel Azo Yellow stood out for its bright, vibrant, yellow glow.
One thing you’ll always read about Quinacridone Gold is that it used to be a single pigment, PO49, until 2017, when the supply of that pigment ran out altogether. Artists bemoan the loss of this pigment which, in retrospect, they imbue with almost magical properties. I’m too young in watercolor years to have tried it, but personally, I love the mixed Quin Gold hues that you can find now, so I’m happy!
