How Finn Sees The World
In the latest ep of Adventure Time, we find out that Finn is Red/Green Colorblind. Also known as Deuteranopia, it is most common in males, especially Caucasian males.
Using a Colorblind Simulator (go try more pics yourself!) these are a compilation of how Finn probably sees the Land of Ooh. Especially interesting is that he doesn’t really see how pink Princess Bubblegum is, or how red Flame Princess is!
Also, here’s an example of why Finn probably confused the Emerald for a Ruby:
Kind of easy to confuse the two in a dark cave.
