25% of the people have a 4th cone and see colors as they are - https://www.linkedin.com/pulse...
"The color nuances we see depend on the number and distribution of cones (=color receptors) in our eye. You can check this rainbow: how many color nuances do you count?" - Mark H
"You see less than 20 color nuances: you are a dichromats, like dogs, which means you have 2 types of cones only. You are likely to wear black, beige, and blue. 25% of the population is dichromat." - Mark H
"You see between 20 and 32 color nuances: you are a trichromat, you have 3 types of cones (in the purple/blue, green and red area). You enjoy different colors as you can appreciate them. 50% of the population is trichromat." - Mark H
"You see between 33 and 39 colors: you are a tetrachromat, like bees, and have 4 types of cones (in the purple/blue, green, red plus yellow area). You are irritated by yellow, so this color will be nowhere to be found in your wardrobe. 25% of the population is tetrachromat." - Mark H
Tested; wife could see 24 colours, I could see 35. - Mark H
36 colours, and it's true. I HATE YELLOW! :D - Deli Bedri
39, but I actually do like yellow (I just look terrible in most yellow/orange, so I don't wear it.) - Jennifer Dittrich
I will admit that the yellow band is the one where I see the least variance - I know there are probably additional different shades, but don't distinguish as many. The blues? All over that. - Jennifer Dittrich
Here is another similar test http://www.xrite.com/online-... interesting to do and it tells you what range you have trouble with. A low score it good. I got a 4 and my poor range is in the greens which surprised me. I would have guessed the reds. - Shannon - GlassMistress
^ Eek Shannon, this one is hurting my head! - Heleninstitches #teamff
i saw 38. - grizabella
I bet everyone's 4chromat ^^ - Alice Cooper
Interesting but not true. 3 cone enough to count 16 millions (2^24) colours. - ParaBellum
Most People have 4 cones. 1 for grey, 1 for blue, 1 for green and 1 for red. Some people's red and Green cones mixed, so they can not recognize red and green. - ParaBellum
37. By the way yellow is my favourite colour:) - mina_sydney
33. Not a fan of yellow for clothing, but I do have yellow items in my kitchen and a few other places. Orange, on the other hand...ew. ETA: viewed the spectrum again on my tablet & got 39. Hmm. - Corinne L
My understanding is that you see greys with rods, color with cones. (Interesting: Wikipedia's article doesn't include a mention of a fourth cone variety, and since Wikipedia's always right...) [36, for what it's worth, and my wife says I have lousy color discrimination. No yellow in my wardrobe; that's for flowers.] - walt crawford
36, though since we can infer where a different color would be I'm not sure how accurate that is. - Todd Hoff
I saw about 37 bands, but "Professor" Diana Derval is an expert in "neuromarketing", aka "marketing". It's worth nothing that even though it's a PNG, there's what looks like JPG compression artifacts which introduce additional, unintended colors about a pixel wide. </grump> - Andrew C (see frenf.it)
Then again, she may have uploaded it as a PNG and LinkedIn's crappy CMS auto-converted it to a JPG, since the filename is "png" but it's actually a JPG anyways. - Andrew C (see frenf.it)
36. And that yellow is awfully bright. - bentley
BTW, wikipedia says maybe 2-3% of the population are tetrachromats, not 25%. </continued-grump> - Andrew C (see frenf.it)
2%, 25%... close enough, right? :P - Jennifer Dittrich
I see about 34, and I hate yellow! - RudĩϐЯaЯïan
38, but I love yellow. - Heather
I'm sorry but some of you have been had: http://www.snopes.com/politic... - Stephen Mack
"some of you have been had" -- I think you mean we've been neuromarketed. - Andrew C (see frenf.it)
I figure any of this stuff is likely to be in the same bucket with the "learn your Meyers-Briggs Horoscope in 4 questions" and "Your IQ: BEST TEST EVER" tests. - Jennifer Dittrich
39? I wear grey. It's soothing. - Meg VMeg
39 shades of grey? - WoH: Professor MOTHRA
Andrew, are you neuromarketing me right now? - Stephen Mack
Book me as a headlining speaker to find out! - Andrew C (see frenf.it)
Jennifer+++ - Stephen Mack
Hey man, don't harsh my superiority buzz. - Meg VMeg
