four color gumbichromate printing...... what pigments to use?

greenspun.com : LUSENET : B&W Photo: Alternative Process : One Thread

I have been pringing gumbichromate prints for years.... specific pigments work better than others for clarity and resolution.... I now want to venture into four color printing. I did a test once in college years ago, but have forgotten which pigments translate the best into 'cyan, magenta + yellow'...... any suggestions?

Also..... does anyone know which chemical works best for a clearing bath, to get rid of the yellow stain after doing multiple layers?

would love some input...... thanks annemarie
