Today's Foxtrot was a paint by numbers with divisibility by 13, 17, 19 or primeness being the color key. I was sitting around bored, so I worked it out. After writing a little script to take a number and tell me what color it was supposed to be.

From Bill Amend's blog, it's obvious I'm not the first one to work it out. One of the numbers (2261) is divisble by both 17 and 19, and he has received complaints already. Go internet.
