So, it looks like Coffee wins out over blue-green for the third main color I will stock at shows.  The lineup will be Floating Blue, Coffee, and Beach.

Floating Blue:

Coffee:

Beach:

Although tidepool and red won out over beach, I will keep beach in my main lineup so I have a nice color variation at the shows.  I prefer to use red here and there because it pops so much- I don’t want it to overwhelm the shelves; and tidepool is in the blue family like floating blue- plus it’s a finicky glaze

Thank you, everyone, for all your help!
