I got 100%, but not with the first time.
It becomes suprisingly easy when you just click the other word than what is displayed,
so I was cheating and was using negative word recognition instead of colour recognition.

I admit I cheated as well, I just remembered the sequence after a couple of times.
The first time I scored 68%.

Interesting. I didn't even think of sequencing it. Shows how human brain comes up with creative problem solving.
 
Ever get into a disagreement with someone about a colour?
They think it's something else and they argue and argue. Then you finally
say you are colour blind. Then they say nooooooo you are colourblind.
When you know damn well that you aren't.
lol

Yes it's X-chromosomal. So if a non-colorblind woman who is a carrier (XnXc) has a child with a non-colorblind man (XnY) the outcomes are as follows:

Non-colorblind girl: XnXn
Non-colorblind carrier girl: XcXn
Non-colorblind boy: XnY
Colorblind boy: XcY
Only boys can be colorblind.

Type 1
So: XnXc x XnY -> XnXn, XcXn, XnY, XcY
Only boys can be colorblind.

Other configurations:

Type 2
XnXn x XcY -> XnXc, XnXc, XnY, XnY
0% colorblind, 100% of girls are carriers.

Type 3
XcXc x XnY -> XcXn, XcXn, XcY, XcY
100% of girls are carrier, 100% boys are colorblind.

Type 4
XnXc x XcY -> XnXc, XcXc, XnY, XcY
50% of boys are colorblind, 50% of girls are colorblind, 50% girls are carrier.

Type 5
XcXc x XcY -> 100% of girls are colorblind, 100% of boys are colorblind.

Type 6
XnXn x XnY -> 0% of girls are colorblind, 0% of boys are colorblind, 0% of girls is carrier


So if we have a thousand of each of these couples and each of these couples would get one child, we would have 6 thousand children.

Couple type 1:
250 XnXn, 250 XnXc, 250 XnY, 250 XcY

Couple type 2:
500 XnXc, 500 XnY

Couple type 3:
500 XnXc, 500 XcY

Couple type 4:
250 XcXc, 250 XnXc, 250 XnY, 250 XcY

Couple type 5:
500 XcXc, 500 XcY

Couple type 6:
500 XnXn, 500 XnY

So we would have out of 6000 children:

750 non-colorblind, non-carrier girls
1500 non-colorblind, carrier girls
750 colorblind girls

1500 non-colorblind boys
1500 colorblind boys

So even though there is a huge and very unrealistically high percentage of Xc-alleles in our hypothetical population, there are still twice as many colorblind boys being born as there are colorblind girls being born.

Sharp Quattron TV

Does Sharp Quattron TV look different than standard RGB TVs to those of you who are Red/Green colour blind.

Is there any move to improve traffic lights?
Seems to me that with LED lights it should be easy to add a white shape in the lights. So Red for example would have a white hexagon outline near the periphery of the light disk.

Every colorblind driver knows that red is on top and green on the bottom.

In the Paleolithic, men were the hunters and women were the gatherers. They had to be able to tell the ripe fruit from the green fruit and the tasty leaves from the poisonous ones. Men went out hunting and the large animals they hunted with spears generally don't bother with camouflage coloration, so they didn't have to figure out what color they were. Maybe that was it.

Alternately, maybe the colorblind gene is on the X chromosome and it's a recessive trait. (Sorry, maybe that info is in here somewhere. I read this whole thread four years ago but I'm not going to do it again.) So the baby will be colorblind if and only if two X chromosomes with the gene double up, and that can only happen in a female.

These are just pure speculation.

I went to highschool with a colourblind girl.

I also know of a pair of identical twins, only one of which could roll their tongue.
 
I just read an article in discover that says that female children of color blind ppl are more likely to see better colors than the normal person..it says that color blind ppl have a mutant cone receptor in their eye that causes color blindness, so when they procreate that mutant cone is sometimes transfered into the female offspring and makes ir so the colors that they see are more..

the normal colors have three cones red,green,blue..color blind usually have one of the cones that have been mutated, so the female offspring sometimes inherit the mutant cones causing them to have four cones and see more colors..

i actually looked for the article so i could link it,but couldn't find it..
guess it was only in the print version of the mag for now..
