Color Blindness in Japan?

[Lopan999]

I have a few questions. I hear that about 5% of Japanese are colorblind or color deficient. (while in America it's about 7%). I knew a few color blind people here in USA.
First of all- how many colorblind people does any know (some one from Japan)?
And is it true that color blind people have alot less privileges in Japan?
I hear that colorblind people can't get into certain schools and many busseness don't hire them.
Any information on colorblindness in Japan would be helpfull.

Well depending on the work it can be a hazard or a severe impediment to be colorblind. I havent met anyone japanese whos colorblind but a mate at work is.

slightly on topic (although in Sweden) one of my best friends is completely colourblind, as in he sees everything only in blacks and whites.. it's very uncommon, but sorta fun to observe him.

I lived with him for a while and had to fix his tv channels cuz some of them weren't properly tuned in... were just black and white..

He also had AMAZING nightvision. he was like a friggin cat.. when i could barely see my hand infront of me, he could make out stuff far away.

And when I tried to hide in a forest wearing army cammo (to test him) he could spot me without any problems.. almost instantly...

however, when i wore the slightly orange suits that have the tree-like cammo hunters wear so deer wont see them, i could stand next to a tree 100 meters infront of him and he wouldnt see me.

lol, funny 5h17.. i suspect that the person with the question is either colourblind... or else someone wanting to go to japan is.

My biology teacher back then at the "Gymnasium" (some sort of high school, but longer) was red-green blind, the most common color blindness.

Here's a site that describes the different kinds of color blindness in detail, including a color blindness test (click on "Testing" on the top bar):
