The perfect lead into my series on perceptual color palettes. Great post!
The original article on the Guardian is here. And here is the conversation that lead to improved map, as put together on Storify.
I thought it’d be interesting to run a simulation of what the map would actually look lie to viewers with the 3 types of color deficient vision. Below are my results for the first map. It is obvious from this simulation that while the map is OK for Tritanope viewers, the green and red areas are very confusing for Protanope and Deuteranope viewers.
The second map instead passed the simulation tests. Here I am showing the original at the top and the Deuteranope simulation at the bottom.
All simulations were done using the Dicromacy plugin for ImageJ. With Vischeck you can do the same with webpages.
Also there’s Color Oracle (http://colororacle.org/) which allows you to perform the simulations on the fly. No need to capture and upload images, just press F5 and your screen shows a color blind simulation.
Hi Gregor
Thanks! The more the tools in the toolbox, the better.
Cheers,

Wow! That’s something useful to know. I don’t know that this crosses our minds nearly as often as it should. How important it is to remember to see things from different points of view.
Thank you for reading and for the comment. I could not agree more!
