I put PFS in my main tank about 2 months ago and the colors of my fish have become lighter. The color change seems pronounced especially on panda cories. Their black bands seem much lighter than they used to be. Some of them now have light grey bands. I assume that their color has changed so that they can better blend with the surroundings. Am I correct?

I agree. Except for some fish like discus that usually look better on light substrate. Some strains even develop dark "peppering" when kept with dark substrate +/or dark background.
