What It Looks Like To Be Colorblind, Part II


Screen-Shot-2016-09-07-at-7.17.37-PM

We’ve linked to posts before about what it looks like to people who are colorblind complete with animated gifs, but there is a new resource of gifs from the U.K.’s Clinic Compare that have a more film like quality and include a wider variety of color blindness forms.  We include a number of them below including green-blind/Deuteranopia, blue cone monochromacy, red-weak protanomaly, blue-blind/tritanomaly, green-weak deuteranomaly, monochromacy/acrhomatopsia, red-blind protanopia, and red-weak protanomaly.

gifs are rather large, so give them time to upload.

Color Blindness: What Does It Look Like?

One of the common questions people have is what it means to be colorblind since that is one of the common visual deficit manifestations that they can relate to.  Color blindness (pretty good article on Wikipedia there) is very common and just about everyone knows someone who does not see the world quite like they do because of a form of color blindness.

I have a post over on Jonesblog that renders some natural scenes as protanopes, deuteranopes and tritanopes would see them and talks about how to simulate your own images for various forms of color blindness.

Was Van Gogh Colorblind?

A friend of mine (and amazing landscape/nature photographer) Jim Goldstein sent me a Tweet and pointed out simmering new conjecture in the art community that Vincent Van Gogh might have been color blind, specifically a protanope.  I seem to remember some discussion of this years ago, particularly given that one can rather nicely simulate both protanopia and deuteranopia in Adobe Photoshop with built in filters (View>Proof Setup>Protanopia/Deuteranopia).  However, the current speculation comes about from Kazunori Asada who wrote up a Tumbler blog entry here describing how he came about his idea and a subsequent app he wrote to simulate color vision and color blindness.  The image above shows Kazunori Asada’s approximation of Van Gogh’s Starry Night and Flowering Garden with Path with the original on the left and the Asada transform approximation on the right.
