Wilsonneal - inking with multi-color inks is just something an individual needs to learn through trial and error - and experimentation. It's not a 1-2-3 ... a-b-c, by-the-numbers technique. I have read most, if not all, the books on bromoil and they all deal with monochromatic inking. I have written a how-to book on the bromoil process, but I don't think I could even scratch the surface on writing about how to ink in multi-colors. It's art ... not science, and it would be extremely difficult to express in the written word. Good question. Poor answer! :>) Gene
