unfortunately humans started using fire a fairly short amount of time ago. 

so possible that we evolved to spot it better, but most likely we were using the same 3 colors now as before.

a way to prove this would be checking to se if other primates that dont use fire still use the same spectrum

idk tho im not a science lol

I meant animals in general since we can all see fire(I’m assuming ). I should have been clearer
