Hi, guys.
I have a bit of an odd request here. I'm doing a project for art school that's based on the seven colors of the rainbow. Now I have this idea of taking a series of seven photographs of differently colored soup being poured out of a development tank. I'm trying to come up with a list of what combinations of developer and film result in which colors. But I'm only one person, and experimenting would take me far too much time. So I'm hoping some of you might know off the top of your head what combinations are needed to take seven photos for red, orange, yellow, green, blue, indigo and violet.
Any ideas?
