what colour is the sky in your world?

i don't remember when the thought first occurred to me. the first recollection i have of it is talking to my brother in the kitchen on le jeune. what colour do you see the sky as? if i was in your head would i recognize it as blue? or would it look green or pink?

we all know the sky is blue because we have been told so. common colours are named, and we have accepted certain archetypal representations to point to. the sky is blue, grass is green, blood is red, paper is white, and so on. but, if i was in your head, would what your brain perceives look to me like that? there's no way to know. maybe if i could see what you see, it would be a psychedelic vision of fluorescent pink skies, blue trees, streets paved with gold, and populated with gray scale people.

could this account for people with a good sense for the visual arts? the colours they perceive line up well with the population average? and perhaps people who have the most aweful fashion sense... maybe it does look good to them... hmmm...

so, what colour is the sky in your world?
