To add to that, to an animal with only two colour receptors (there are a lot of them), just RG might look white.
Or to be more precise, for them instead of equal proportions of 560 nm/530 nm/420 nm light being white, their own white might be something completely different like 550 nm/460 nm depending on their photoreceptors. Which would absolutely not look white to us. And mantis schrimps would need equal proportions of 16 different wavelenghts to see what they could call white.
