## What is Sketch Swap?

Discover the world through the eyes of someone with colorblindness. 

Draw and color using a palette of colors filterd to appear as they do for a color blind person (three options available), and see the daily difficulties faced by people with colorblindness.

After drawing you can can then swap the colors to 'normal' and reveal the differences in perception between colorblind and conventional vision.

Use pre set templates or free draw.
