very recent study, and a very interesting one
That is interesting, although I didn't read all of it. Too tired to even try to understand it all right now.
Everyone being descended from one blue-eyed person makes sense to me, except for the fact that blue eyes are a recessive trait. Did they explain somewhere in the study why blue eyes didn't die out immediately with the first person?
I should add that females can distinguish more colours in the red/orange range compared to males. Apparently women gathered flowers/fruits/leaves etc. while the men hunted animals which were less colourful, whilst we were evolving.
Women generally have better/more vibrant colour vision because they have more cone cells in their eyes. Men have more rod cells, so they can generally see contrast better. Also, apparently due to some sort of abnormality on the X chromosome, some women are tetrachromats:
http://en.wikipedia.org/wiki/TetrachromacyI think that there is a good argument for light-eyed people being overly sensitive to light (might be interesting to research someplace where blue eyes are very common, see if it's less damn shiny.)
I think this is bullshit. I have verry (verry) dark hazel eyes (mostly dark chocolate brown with an extremely dark green ring) and my eyes are light sensitive. To the extent that i have photo-sensative lenses in my glasses that change shade (from clear to verry dark sunglass colour) depending on the brightness of the light hitting them. This is because otherwise i get constant miagrains, eye pain, tempory blindness and watering eyes i can't hold open, in bright light or whilst looking at especially bright colours or shiny things.
So from personal experiance i see a big flaw in that argument. I think it's person to person and gender related rather than anything to do with your eye colour.
He didn't say anything about dark-eyed people all being less than over-sensitive. Only that light-eyed people are more often. I have blue eyes and also own a pair of Transition lenses. Handy, aren't they?
Anyway, back to the choosing palettes topic: I usually select my initial palette colours by picking straight off of the board and rounding the RGB values to the nearest multiples of 5, but if I edit the colours later, I use HSL to fix them up.
