I have not worked with colored papers, but that strikes me as a good point.
I did have trouble getting good contact prints with Dylux paper for some
modern papers that had been treated with various coatings, and also with
papers that had been waterstained, which apparently makes the paper become
more dense as it dries and reduces the contrast between watermarks and the
rest of the paper. So I can imagine that you could have trouble getting
good prints with the Dylux method from colored papers.
