Thanks for the info update...can't answer on the color...we are still trying to decide who is getting what color here!

So far we have decided:
Mystery will be getting Blue
Naomi will be getting purple
Asia will be getting pink
Ember and Indy the calico's may both be getting red.

I was going to do red on Indy and clear on Ember...but then my daughter Karissa pointed out that we may not notice if and when a clear one sloughs off...so she wants both the calicos to have red.

Anyone interested in a link to buy the clear caps in larger quantities - here you go:
PetEdge.com

Just put nail caps in the search box at the of the page.
