After a chat with his color deficient friends about how Vincent van Gogh’s paintings seem to appeal to all eyes, Kazunori Asada used visual filters to see how the paintings looked to the colorblind. The experiment produced some interesting results and musings:
Was van Gogh partially color vision deficiency (anomalous trichromat)? Perhaps using a strong color vision deficiency (dichromat) simulation was the wrong approach. How about carrying out the simulation by removing the middle portion of normal color vision, maybe then I could see van Gogh’s pictures in a better light?
The color choices for van Gogh’s popular paintings seem less out there with the filters. The greens in the sky of Starry Night, for example turn to yellows.
A colorblind van Gogh though? Probably not. Either way, don’t forget to pick your colors wisely. Asada has an easy-to-use tool to see what your own images look like to others.
