poliphiloMale and female blue tits look just the same to us but not to one another. That's because they can see colours we can't- and male blue tits carry brighter patches of ultra-violet.
(I got this info from Chris Packham's excellent TV show World's Weirdest Events.)
Ultra Violet is a real colour- or range of colours. The same goes for Infra Red. But I can't see them. I can't even imagine them. I find that very hard to get my head around.
