Color perception arbitrary?

[Rahul]

I dunno, but colour causes too many arguments in this place. Despite neither of us being colourblind, my sister and I apparently see some colours differently which has led to some pretty ridiculous arguments about what colour some things are.

The biggest one being about the green (definitely GREEN) wrapping paper I used for her gifts at Christmas, which she insisted was blue. It was fucking GREEN!
And my RED umbrella is NOT fucking pink.

I read some article about a year ago that a certain percentage of women can see more colors in the red-brown spectrum than everyone else. No men can say the same about this ability.

So if you have a female friend that has what seems an over abundance of brownish boots, purses, coats, or whatnot, they may be one.

I've become convinced my wife is one of these women.
