Watercolor pigments - pigments to avoid...

I dont usually post on here. Mostly just read and search when I have
a question.

so hello and hi.

Im curious if there is anywhere online or such that lists the
different watercolor pigment colors and whether they are good too use
in Gum Bichromate printing.
IE they dont stain or whether they are lightfast or not...

thanks in advance for any info.
