Jan 26 – color matters
Posted by Dave Bath on 2011-01-26
I just discovered that January 26 has a significant event, and that color is the issue, and will be remembered all around the world.
OK, not really that significant: Facebook End Colorblind Confusion (For a Day…) – "please" attend by wearing an uncolored shirt – white, grey or black.
Yep…. we aren’t colorblind, we are color confused, we’ll mix them up, give them the wrong name, have trouble if they are similar saturations… (resources to test and simulate what we see over the fold)
So as an example of the 1-in-20 males with characteristics essential to survival of the human race a hundred thousand years ago, the guy in the hunting party who wasn’t fooled by mainstream camouflage, the one who said "throw your spears and rocks over there" at something we wanted to eat, or wanted to eat us, I offer a few giggles, hopefully for all of us, although for different reasons.
Now, I’m told I might need to be careful with one of the following images – but I cannot tell which for sure.
More images, and some references to tests and simulations so you normal folk can see what we see over the fold.
But if you design a website with color-coded buttons – if your graphs use lines with reds and greens of similar saturations (especially thin lines) – I hope you burn in hell.
- Doing the right thing
- What is it like to be colorblind? – some simulations for those with normal color vision:
- Some Tests
- A link to a few very different tests
- A novel one from city.ac.uk – watch the vid, and the moving color region disappears for a second… you are probably one of us.
- A good quicky version of the Ishiharas
- A reasonable test that gives probabilities with the results of yours truly:
- Estimate of color vision deficiency’s probability: 84%
- normal answers: 19/31
- Your answer is randomly: 0/24
- no similar proposal: 2/7
- green color deficit (deuteranopia): 8/17
- green color deficit (deuteranomaly) simulation wickline: 0/7
- red color deficit (protanopia): 1/13
- red color deficit (protanomaly) simulation wickline: 0/7
- blue color deficit (tritanopia): 1/12
- blue color deficit (tritanomaly) simulation wickline: 0
