to prove this take a blue light and shine it at a banana.It will turn black.FrothyChimp said:Paint works by absorbing colors and reflecting only specific wavelengths. Add enough colors together and you get something that absorbs most of the wavelengths. Light is not absorptive. Each wavelength impacting the cones of your eyes stimulates the transmission of that color. Add a bunch of wavelengths across the spectrum and it begins to look white because the combination is additive.

Unless it floressence, like shine a blue (473nm) laser in a white LED (its yellow inside) and you'll get a white-ish colour.

Btw, I think that's a gas laser , lasing at multiple lines, not RGB combined.
