Who remember's playing with Crayola crayons? I distinctly remember tearing off their paper wrappings so that I could color using the sides of the crayons instead of just the tips. Why? I have no idea - I was a kid.
Anyway, if you're curious as to how the colors of Crayola have evolved over the years, here's a neat visual representation from "Weather Sealed"
Apparently, the number of colors doubles every 28 years! Rad!
