Just so you know, one of the pigments in that paint, basic violet 10, is
fugitive. (The other pigment is PR122, quinacridone magenta).

Actually that's PY34... PY24 is Flavanthrone which isn't used in any
watercolor paint.

I've used viridian and chromium oxide green, both chromium paints, with
no problem. I'm convinced that's just another myth.

That's why you can't go by paint names, of course, because paint names
often have nothing to do with the pigment that's used. It's odd, though,
isn't it, that manufacturers will retain the names of fugitive and toxic
pigments and give them to safer more lightfast ones. Doesn't make a lot
of sense to me. cheers,
