The process in this case is âsubtractive,â since the pigments subtract or absorb some of the wavelengths of light. With transparent dyes, like our Fiber Reactive Dyes that we use for Tie-Dye, Cyan (blue-green), Magenta (red-violet), and Yellow and are called subtractive primaries, or primary colors.he process in this case is âsubtractive,â since the pigments subtract or absorb some of the wavelengths of light.
