What does the world look like when you're color blind?

On the left is a picture of me with my bike, taken by my friend Laura Kling. On the right is the same image, as it would be seen by a person with protanopia — a relatively common (as in, still very rare) form of color blindness that affects the ability to see green, yellow, and red colors.

The Color Blindness Simulator will allow you to do this with your own photos.
