So when you were a kid, didn't you always wonder why a Crayola crayons box had so many shades of brown in it?

In a box of 48 crayons, there were burnt umber, sienna, crimson.

In a box of 100 crayons--and yes, I knew a kid who had such a treasure--there were two shades of cinnamon, amber, tan, beige, scarlet.

Only as an adult do you realize why you would need such an infinite variety of colors that seem to be drawn from just one corner of the palette.

It's called ... Fall.
