I think he meant flashing the paper with a specific color before projecting the image onto it to get a tint in the shadows. I was looking for that for a long time cause I didn't know how to do that with an enlarger so thanks. I'm still not certain about the color range though, I want to achieve a look similar to screen prints, where there is very little gradient, less color rich. I'll try the tissue method, but I still don't get what it does to the projected image, I think it just softens the edges, but does it make the colors less striking?
