Today I found the claw of a blue crab, and it got me thinking.  Did I have shells in every color of the rainbow?  I decided to try and make a "beach color wheel".

I had to cheat a little, because really I only had the one blue crab claw.  So I threw in some blue and green sea glass as well.  I did have a green shell--maybe that's algae on there, I'm not sure.  There are plenty of reddish-orange and orange shells, I find orange jingles all the time.  And orange scallops.  The purple shell at the top I've only ever found one of, and I'm still trying to figure out what it is.

Note: I have since discovered that the purple shell is a Delphinula, or Dolphin shell!
