Colours are reflected light. They're what bounces off something, the light is not the same coming off of the surface as it was going in.

So, logically I guess primary colours absorb green light. Or something like that.

yes and NO
Visible coloured light is e/m radiation betwenn about 350 and 720 nm wavelength ( some people`s eyes do a little more and a little less but that is a very good approximation) reflected or directly received matters nothing.
