The red and blue mix is lighter too, a beautiful magenta. (Spoiler: We're about to get into secondary colors!) "When the blue flashlight circle intersects the green one, there is a lighter blue-green shape," he says. The subtractive primaries also modulate red, green and blue light, but a little less directly." The additive primaries do this very directly by controlling the amounts of red, green and blue light that we see and therefore almost directly map to the visual responses. Those are roughly sensitive to red, green and blue light. "That is to modulate the responses of the three types of cone photoreceptors in our eyes. "Both systems are accomplishing one task," says Mark Fairchild, professor and director of the Program of Color Science/Munsell Color Science Laboratory at Rochester Institute of Technology in New York. This leads to two types of colour mixing, additive and subtractive." "Light enters our eyes in two ways: (1) directly from a light source and (2) reflected from an object. "We see because light enters our eyes," he says.
Stephen Westland, Professor of Colour Science at the University of Leeds in England breaks things down into simple terms, in an email.
