Count the colours

Count the colours

Simple, right? Just count the bands of different colours in this picture. Disregard compression artifacts. Do it visually (as in, don't inspect the numerical values of the pixels - that doesn't work anymore because jpg). Bands not near each other can be assumed to be of unequal colour (it's a rainbow).

I'll go first because OP: 37

Mhhh 37 too

Some biband of color, but it is pretty much seeingable.

u/ben_g September 03, 2015, 02:54:02 PM

I think I see 39. Is this a test to check your monitor calibration?

u/Snektron September 03, 2015, 03:15:53 PM

Nah its an eye test. like if so see a low amount (like 20 or something) you have 2 different cones, around 30 three and 35+ four.
There are 39 total, so just subtract the number of doubles from it. Though i'm fairly sure it doesn't work at all.

Also fyi this test was already on 9gag an the like a few months ago

Mhhhh four cones people must be girl (with one parent having daltonism) as I know so ...

There is problem somewhere...

EDIT : and they see more color in yellow.

My dad has daltonism, but as far as I know I'm not a girl

Anyway, how could a test that checks for 4 colours even work on a monitor that only has 3 base colours?

u/TheMachine02 September 03, 2015, 03:25:06 PM

Yeah. It would need a 4 colors monitor

u/Snektron September 03, 2015, 03:27:01 PM

Maybe it tests tranparency

u/ben_g September 03, 2015, 03:28:46 PM

With a jpeg? Yeah, right XD

u/Ivoah September 03, 2015, 03:34:06 PM

I'm colorblind, so

u/Snektron September 03, 2015, 03:36:22 PM

Yeah, im a bit colorblind too. Yet i can see like 36 colors.

Girls are less exposed to Daltonism/color blindness because the gene that causes it is a recessive gene on the X chromosome. Females have two, so they have a backup. I also know tetrachromats are mostly female for the same X chromosome reason but I forgot the exact explanation.

Anyway not counting the colors when I can see smooth gradients.

Effectively it tests monitor calibration as well as your eyes of course, and old 6-bit LCDs would be at a significant disadvantage..

Also the test is probably bullc, but who cares right

u/novenary September 03, 2015, 04:45:30 PM

Hehe yeah, the test is definitely bullc with jpeg compression.

u/Yuki September 03, 2015, 09:50:01 PM

I count something like 40. But even without the bad JPEG compression artefacts, this test is bad and you should feel bad.

I recommend this test, which is way better: http://www.xrite.com/online-color-test-challenge (I got 0 once!)
