Test your colour recognition!

Found this test on another forum.

Found it interesting and fun.

Follow the link and choose your country, then rearrange the tabs in order.

Sounds easy.

I tried it and got 16, then tried it with my screen brightness up... got 0.

The lower the score the better.

My eyes still hurt...

Blimey - I see what you mean - must have something to do with the quality of your computer screen as well surely ?

I got 7 - not bad for a 63 year old - and yes my eyes are flashing too

I got 7, found the 3rd bar the hardest to do. I got the first and last bars perfect, 3 mistakes in the second and 4 in the third

Edit: Actually, I just had another fiddle and in fact both my mistakes were in the 2nd row, even though I thought the 3rd row was harder I eventually got it right. Apparently 2 mistakes is worth a score of 7, I'm sure theres a reason for that which is currently escaping me.
you don't have to be mad to post here

but it does help

I managed a score of 6 on a TN panel TFT.

I agreed the third bar was the hardest, but, TBH I don't have the patience to do it again to check different screen settings or know where I went wrong. At least, not just now. *laughs*

Interesting. I scored 3.

This should be interesting too, when I have time to read it.

15 I got on the MacBook screen. Have to try on the desktop...

Father Ted: I also had some problems finding it at first. Looked around a bit (and had German and English mixed; English OS on the Mac).

If you have a high score then try this test to see what of color vision deficiency you have.
It comes from Wikipedia

#1 if you can not see the number 37 you've Protanopia

#2 if you can not see the number 49 you've Deuteranopia

#3 if you can not see the number 56 you've Tritanopia

#1 Protanomaly (1% of males, 0.01% of females): Having a mutated form of the long-wavelength (red) pigment, whose peak sensitivity is at a shorter wavelength than in the normal retina, protanomalous individuals are less sensitive to red light than normal. This means that they are less able to discriminate colors, and they do not see mixed lights as having the same colors as normal observers. They also suffer from a darkening of the red end of the spectrum. This causes reds to reduce in intensity to the point where they can be mistaken for black. Protanomaly is a fairly rare form of color blindness, making up about 1% of the male population. Both protanomaly and deuteranomaly are carried on the X chromosome.

#2 Deuteranomaly (most common - 6% of males, 0.4% of females): Having a mutated form of the medium-wavelength (green) pigment. The medium-wavelength pigment is shifted towards the red end of the spectrum resulting in a reduction in sensitivity to the green area of the spectrum. Unlike protanomaly the intensity of colors is unchanged. This is the most common form of color blindness, making up about 6% of the male population. The deuteranomalous person is considered "green weak". For example, in the evening, dark green cars appear to be black to Deuteranomalous people. Similar to the protanomates, deuteranomates are poor at discriminating small differences in hues in the red, orange, yellow, green region of the spectrum. They make errors in the naming of hues in this region because the hues appear somewhat shifted towards red. One very important difference between deuteranomalous individuals and protanomalous individuals is deuteranomalous individuals do not have the loss of "brightness" problem.

#3 Tritanomaly (equally rare for males and females [0.01% for both]): Having a mutated form of the short-wavelength (blue) pigment. The short-wavelength pigment is shifted towards the green area of the spectrum. This is the rarest form of anomalous trichromacy color blindness. Unlike the other anomalous trichromacy color deficiencies, the mutation for this color blindness is carried on chromosome 7.[17] Therefore it is equally prevalent in both male & female populations. The OMIM gene code for this mutation is 304000 “Colorblindness, Partial Tritanomaly”.
