I have been encountering a very strange behaviour with the ieeecolor.cls document class! Compiling a latex document using this class with the tikz package triggers some color warnings: Warning Incompatible color definition, but the pdf generated seems to be as expected (i.e. see MWE below).
However, very odd things happen when the following section is added to the tex file:
%%%% Inverse PDF page and text color
\definecolor{pagcol}{rgb}{0.1255,0.1255,0.1255}
\definecolor{txtcol}{rgb}{0.85,0.85,0.85}
\pagecolor{pagcol}
\color{txtcol}
In this case, the behaviour of latex is rather unexpected and the colors are not as they should anymore. This seems to come from a clash between the new ieeecolor class and some packages like tikz.
Has anyone encountered this issue before? Has anyone find a fix for this?
The ieeecolor class can be found on the IEEE Author Centre Website, it requires the files ieeecolor.cls and 'generic.sty'.

ieeecolor.styis a bit of a pain in the back. BTW, does anybody know who can be contacted to post patches?There are two technical problems here, and one philosophical thing.
The philosophical thing is: is it worth caring? When they accept your paper, they will re-format it with something that's not LaTeX at all, and they want separate figures anyway, which are better build with
standalone. But if you want your file working for internal use or submission to some archive, then yes, maybe it's worth it to care.The technical problems are two:
color, notxcolor(in 2021!), which is why you have all the problems with TikZ, which requiresxcolor.Possible solutions.
ieeecolor.clsThis should fix both problems, I think.
ieeecolorby loadingxcolorbefore the class; fix the other problem with Phelype Oleinik fix: just change your invocation of\documenclasswith (tested using theieeecolor.clsdownloaded this morning!):Both seem to work for me, but I had no time to check deeply.
