Reply to comment by neku in If light is just electromagnetic waves, and color is just different frequencies of light, and we can make radio waves at arbitrary frequencies, why can't we create visible light of arbitrary pure colors? by flabberghaster
No they use three different color lights and mix them at different intensities and it looks to our eye like that color. What I mean is why can't we create arbitrary, single frequency colored lights when we can do that with radio waves? Is it just because we don't know how to do it in that range?
