Test your colour recognition!

Anvh, I can just about see a 3 in the first one, sod all in the rest, might have to stop driving, ( always wondered why people were "flashing" me at the traffic lights, I thought they were just morons.

No point in me getting one of these fancy coloured K-x camera's then

Scored 4, but it's about midnight and a bit sleepy. No any adjustments to my monitor (Samsung SyncMaster 970P) - but it reproduces colours nicely I think.
Kind regards,

With the colour discrimination test in the original post, how much does the monitor quality or calibration matter?

Increasing brightness and contrast may make a difference to allow a user to discriminate between two close colour, but ...

If a monitor is skewed towards a certain part of the spectrum it will have an effect on all of the colours and a user should still be able to sort them correctly. Unless you have a graphics card that only does 4bit colour!

As an analogy - sort 10 consecutive numbers into reverse order. Now, it would not matter if the numbers were 1 to 10 or had an offset of 0.2 and went 1.2, 2.2, 3.2, ... or a 20% offset so, 1.1, 2.2, 3.3, 4.4 ...

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...

Very interesting test. I'm going to get my wife to do it as we're always disagreeing when it comes to colour.

I scored 8. Not bad for a 68 year old I reckon

I scored 69!

And I can't see the second of Stefan's pictures so I probably have Deuteranopia then. That's a bugger, I'm sure I was healthy when I woke up this morning...

FWIW, I scored about 30. I then profiled and calibrated my monitor using ArgyllCMS and a Huey and tried again ....... and scored about 30.

I also seem to have Deuteranopia, ho hum ..........

Scored 23 but I did it quickly on uncalibrated laptop. However, I did this integrated test and found 92% on the deuteropic one. 100% OK on the others. A second go gave 100,100,97 so I'm confused now. My wife claims I can't tell green from blue sometimes.
Lurking is shirking.!
