Incredibly stupid experiment. As someone who is red-green color weak, just as 10% of the male population is, I feel insulted by the implication of this article and the obvious glossing over the fact that not all humans see green/red very strongly. This is lazy science, seriously asking people to differentiate between images of apes that want to mate? It made no sense, you basically proved that some people are colorblind... ok. Did you plan and write this over a weekend? Why did you even bother?
