Since you don't have filters between the layers to block specific wavelengths, you need to make a mixture of emulsions, each of which is sensitive to specific bands. And the spectral sensitivity chart of each of these emulsions wouldn't be "bell-like", as it is with today's color films, but rather steep and flat. Did I get it right?
