i know there are already a lot of posts here...but I have decided to give my 2 cents anyway lol!
Since you already have light blue and tan layers, I suggest:
Darker brown eggs---
Marans, welsummers, barnevelders, penedesencas
Olive eggs---
Isbars, olive egger hybrids
White eggs---
Leghorns, polish, etc etc...I came up with this list a while back.
More tan eggs---
My favorite tan egg layer is the sapphire gem. Not cold hardy, but they are the sweetest.
Faverolles lay pinkish eggs, and croad langshans lay eggs with a purple-ish bloom. I doubt you'll find these unless you order online.
