So, your actually saying that my prints probably are a bit foggy today because of my white easels, and I can get better details and brilliance in the highlights if I paint my easels black?

If so I better paint them right away :-)

The effect of the white easel can be compensated with less exposure and more contrast, which is what you probably do instinctively anyway. The only risk, don't mark your prints on the back prior to exposure, as that may leave a tell-tale sign in the print emulsion.
