The safest, I think, is by defining \color such that it also sets \normalcolor. But I didn't inspect where \normalcolor is used elsewhere (in the kernel and in packages) so I don't know about the possible sideeffects. Maybe \@eqnnum is indeed safer, but then we should have an \AtBeginDocument structure that copies that commands from all math packages around and modifies them. So like if amsmath loaded then \@eqnnum=... if... loaded then ... et cetera. But it's all just guessing. Further inspection is definitely necessary. Anyway, I'll forward this to the author of xcolor. > Have a nice weekend. Thanks, same to you. Best, -Hendri.
