Color mixups
Hi, I'm way late to this thread and wouldn't bother responding except that I think the indiscriminate (and no doubt inadvertent) use of marketing labels instead of pigment names has made this discussion difficult to follow, and may be worth a comment. I'd say by Rob's recent gallery submissions that he's doing fine whatever yellow he's decided on, but just for future reference, one should go by the Color Index pigment names and numbers, not by the name the manufacturer gives the paint, because in many cases there's no connection between the marketing name of the paint and the actual pigment that's in it. For example, Rob refers to "Quinacridone Gold" that he's tried and been disappointed with, but then goes on to indicate that his "Quinacridone Gold" contains no actual "Quinacridone Gold" (PO 49)pigment, so it's no wonder that he's disappointed with the results, compared to someone who is using actual Quinacridone Gold pigment. Manufacture of PO 49 ceased in 2001; Daniel Smith bought up a large supply of the remaining pigment, and Daniel Smith is the only paint manufacturer still using PO 49; everyone else ran out and discontinued using the pigment by 2005. Any paint now sold under the name Quinacridone Gold by any manufacturer other than Daniel Smith is not actually Quinacridone Gold, and will most likely be a convenience mixture of other pigments mixed to sort of simulate the appearance of Quinacridone Gold, but the mixture will not have the authentic appearance or behavior of the actual pigment. When working with pigments, it helps to know what *pigments* you're working with, because they behave very differently.
