Each wave has a wavelength or frequency. ... This article is about visible light.In additive color mixing, like light, all the colors combined create white. Consider a prism and imagine the process in reverse. In subtractive color mixing, like paint, allthe colors combined create black. This is because you've effectively blocked allother colors.
