If you only associate Vincent van Gogh's name with a severed ear, you should know his works. Through his paintings with expressive strokes and bold use of vibrant colors, he is considered one of the greatest and most influential painters in world history. However, according to one vision expert, analyzing his works through a filter that simulates color blindness gives evidence that he was probably suffering from this dysfunction. See an example below:

Left the original image, and right with the filter applied

Considering the way he used the colors in his works, it seems crazy to say that van Gogh was colorblind, but according to vision expert Kazunori Asada some of the clutter and unreality of the paintings add up if the shades of red and green are softened.

Through a filter that simulates color blindness, Asada analyzed various works by the Dutch painter and noticed that the changes were subtle, but existed, and made the paintings make more visual sense. He said in a blog post that despite the intense use of color some lines of different colors existed side by side, or just a point with different color appeared randomly. And as soon as the filter was activated, these differences silently disappeared, making the work less rough and incongruous.

Kazunori has a Tumblr with several posts (1/2) where you can see various works by van Gogh in their original aspect and with the filter that simulates color blindness. The analyzes were made through an application, developed by himself, that simulates the vision of a person with color blindness. This allows you to view any environment with the color filter through the camera phone. You can download the app for iOS and Android.

This assumption does not alter the beauty of his works or van Gogh's influence on many other artists, but by comparing the images they really get clearer. So, do you think that color blindness had an influence on your works? Leave your opinion in the comments.
