As a note to avoid confusion, Holbein’s Artist Line has a handful of similarly named colors. It’s unlikely to mix up Permanent Yellow Deep with any of the other permanent yellows. However it’s good to note they also have a Permanent Yellow, a Permanent Yellow Pale, a Permanent Yellow Light, and a Permanent Yellow Lemon.
