OH, this is cool to know! Thanks, Dave. That's exactly what was said when I
used them, that they were graphic designer colors used for posters for
reproduction, and that the quality of the pigments was not up to snuff.
Glad it has changed since then.
PS Has anyone used egg tempera paint in tubes and dichromate? If egg
(colloid) is also hardened by dichromate, wouldn't that work? Or is this
what *is* used in tempera printing?
