Lecture 23: Color Science (78)

With the combined wavelength, only the middle has the overlap of green, does that overpower the combined wavelength to appear green and that's how we see the combination of light? Does light distributions of color differ from paint color, since (0,0,0) is black in RBG since it's no color but in paint colors, no color is white.

Light distributions differ from paint because light is additive while paint is subtractive, which is just a result of why paint appears the color it does versus light. When two different wavelengths of light combine, their waves constructively interfere to produce a different wavelength of light, in the case of this slide blue and yellow forming green. Blue and yellow make green because they are "averaged out" to the green wavelength, which is in between them. On the other hand, paint and other colored media actually just selectively absorb wavelengths of light. So you can imagine if you mix a bunch of different paints that selectively absorb the entire visible spectrum, you'll end up with black.
