A colleague of mine sent me the link below. It is kinda fun. Please give it a try.

It will tell you how well you can differentiate between colors and their subtle nuances of tints, shades and tones.

Might be fun for folks to post their score. My best so far is "35" which is not very good. Yikes!

thanks for sharing, I got a 43. Maybe I should find a new hobby where color doesn't matter, yikes.

21 and it appears as if someone slipped some acid into my drink about half way through line 1. :wh

Not even going to attempt it, I'm color blind, light red, light green and light brown, they all look the same.:e3, thank god I have a wife that can see the color spectrum

Surely someone out there can get a perfect 0 ? :2

7 for me on an uncalibrated and cheap work monitor. My brain hurts now :)

I got a 12. Fun to do and a good test.

I seem to have two particular ranges where I have some issues. Now if I could only remember the ranges.

I remember this posted previously. I gave it a another full go- once only - score 4.

My first time doing this was on old monitor at the office and I got perfect score, then I tried again (just for fun) on my Mac at home and I got 21. Maybe it's time to do some calibration or my eye really getting worst after half a day :(

No even going to tell you what I got.. PS: it's over 50

11 on an uncalibrated monitor. Not bad for an old guy.

I am color blind too - which probably explains my score of 69 - eeek!! :eek:

What I have found out is that there are 3 forms of color blindness.

There are three basic kinds:


Completely monochromatic vision, where two or three of the photo pigments in your eyes cones are missing.
Dichromacy occurs when you’re missing a pigment: red (protanopia), green (deuteranopia) or blue (tritanopia).
Anomalies occur where one of your cone pigments isn’t quite right and doesn’t have the right spectral sensitivity, resulting in a reduction of your ability to discriminate colors. The red and green pigments are the most similar so it is easier for differences in them to impact the ability to distinguish colors. Protanomaly occurs when you have a slightly shifted red sensitivity, deuteranomaly (what I have) occurs when your green sensitivity isn’t quite right. Tritanomaly is uncommon (as is tritanopia) and this occurs when your blue pigment isn’t right. This makes blue-yellow discrimination difficult.

I share your sufference with deuteranomaly - I never knew until I applied to join the Royal Air Force.
It has really never affected my life, but I rely on forums like this to let me know when my colours are 'off' in my images.
My wife gets the final decision when I am buying clothes. Otherwise the only time I am really aware of it is when we are with my nephews and nieces and they get the Ishihara tests online to see how silly Uncle Alex is!

Daaaang! That must suck.....

I have a green/brown color blindness I knew about.

But it looks like my color acuity is lousy well beyond just that one I knew, since I also scored well over 50. (I feel a slight bit better because the random chart I started with scores over 900!)

This was really cool and not easy at all. I got a 15. The subtle nuances are really tough to detect.

it's a bummer for sure, but the fun is all in taking the picture:bg3:

Hmm very interesting. All my errors were together in the middle of the robin's egg blue range. Score 7
