if you google hen egg colours you might get a list from someone. or try the practical poultry forum.
I get pale beige eggs from light sussuex, hybrids, ixworths and faverolles. darker brown eggs from marans and welsummers. white eggs from leghorn hybrids. pale blue/green eggs from legbars and legbar hybrids.
I just like to see a tray of multicoloured eggs. They all look the same in the pan.
