Art lovers have gazed amorously at the works of Dutch painter Vincent van Gogh for the past century. Now, thanks to a tool developed by Japanese vision expert Kazunori Asada, we all might start looking at his famous paintings a bit differently.
Asada created the Chromatic Vision Simulator for iOS and Android to show what images look like for people with one or more defective sets of cones, the structures in the eye used to see color.
When examining the works of van Gogh, Asada was shocked to discover that the works appeared the same — if not better — when cast under the Chromatic Vision Simulator.

“This painter has a somewhat strange way to use color. Although the use of color is rich, lines of different colors run concurrently, or a point of different color suddenly appears. I’ve heard it conjectured that van Gogh had color vision deficiency,” Asada wrote in a blog post, earlier this month. “However, in the van Gogh images seen in the color vision experience room, to me the incongruity of color and roughness of line had quietly disappeared. And each picture had changed into one of brilliance with very delicate lines and shades. This was truly wonderful experience.”
