If I knew all of the colors that had been "called" already I would post them all.
Here are the ones I know for sure are spoken for:
Orange
Green
Yellow
Baby Blue
Red Hash Marks (I'm not going to ask if and how he might mark his underwear)
I know there has to be more, if so please add to the list.
Hey, now! Everyone does dots. I use a paint marker instead of a pen. Gotta be different....
