Guys slightly off topic, but please do keep the colorblind people in mind. The colors used for the graphs are so similar that I can not differentiate them.

- fossuser 12y agoInteresting - I thought it'd be red/green, but it's blue/purple (which I thought were colors chosen for the color blind). Is blue/purple color blind less common? Can you differentiate between red/green?
- Sanddancer 12y agoIf you're red-deficient, then purple/blue is also a bad choice for colors because you can't see the red components of purple.
- pkulak 12y agoBlue and purple are the same color as far as I can tell.
- DigitalJack 12y agoRed/blue would be safer colors to differentiate for many colorblind people. Red/green colorblindness is so common it baffles me that comparisons using red/green are still so prevalent. Especially considering how heavily biased the tech population is toward men. And as Sanddancer points out, any colors that make use of red/green are going to be problems as well. (hence blue/purple being an issue as the difference is the red component). In a given group of 5 men, you have a 50% chance that 1 is red/green color deficient.
- Swizec 12y ago> In a given group of 5 men, you have a 50% chance that 1 is red/green color deficient. Soooo, 1 in 10 men are red/green colour deficient?
- schrodinger 12y agoI believe that implies 1 in 8 people are. Pc = Probability that someone is colorblind (1 - Pc) = Probability they aren't colorblind (1 - Pc)^5 = Probability that no one in group of 5 is colorblind 1 - (1 - Pc)^5 = Probability that someone in group of 5 is colorblind Solve .5 = 1 - (1 - Pc^5): http://www.wolframalpha.com/input/?i=.5+%3D+1+-+%281+-+p%29%5E5 http://www.wolframalpha.com/input/?i=.5+%3D+1+-+%281+-+p%29%... You get .129449, which is approximately 1 in 8
- schrodinger 12y agoAlthough wikipedia shows 7% of males, meaning a group of 5 would have a 30% chance of one of them being colorblind.
- Uhhrrr 12y agoI will let others dissect the different probabilities for at least 1 and for only 1 and say, yes! Nearly one in ten: http://www.colour-blindness.com/general/prevalence/ http://www.colour-blindness.com/general/prevalence/ It usually doesn't come up in conversation. Even when I was working on an image processing toolkit, it was several months before I realized my boss was red-green colorblind.
- claar 12y agoPurple is blue+red, so my son who has a very common color deficiency can't tell purple from blue at all. They look completely the same to him.
- trhaynes 12y agoI'm red/green colorblind and blue/purple is the worst combination for me. I colored all my skies purple in elementary school because I couldn't tell the difference.
- awfycooper 12y agoPlease excuse our ignorance. We've updated the chart to try and help you differentiate between the two.
- saidajigumi 12y agoTools like Color Oracle[1] are great when checking UI color design for its color safety. Some monitor software also has similar features. E.g. NEC monitors' MultiProfiler tool supports a number of different color vision emulation modes; see the "Color Vision" pane in that app. [1] http://colororacle.org/ http://colororacle.org/
- NateDad 12y agoWow, great link, thanks!
