“It’s an app that helps colorblind people distinguish color combinations that they would normally have trouble telling apart,” Tom Overton, the creator, said in a Microsoft blog post. “For example, since I have difficulty distinguishing between red and green, our app makes reds brighter and greens darker so that the difference is more obvious. It replaces difficult color combinations, like red and green, with more easily distinguishable combinations, like pink and green.”

Again, this sounds especially appealing to me, a colorblind person. I didn’t realize I was colorblind until I was 15 years-old. (It wasn’t all that surprising, since one in 12 men are colorblind.) My diagnosis came during a routine eye exam, when an optometrist showed me some cards with different colored dots and splotches on them. I was supposed to see numbers and letters within the dots, but I couldn’t see oddly shaped circles. It hadn’t affected me until then—and it didn’t affect me too much after—but it was slightly frustrating knowing I was missing out on the full spectrum of vibrant color life has to offer. The first time I tried colorblind glasses reinforced this mild frustration.

The app is super simple. It offers three modes, one for each of the three most major types of colorblindness: red/green, green/red, and blue/yellow. There’s also an option to turn off the color correction, so you can easily swap between what you normally see and what a non-colorblind person sees and contrast the differences. Although the Color Binoculars didn’t actually make me any less colorblind during my few minutes of testing, it was pretty cool to see things in full color, for once.
