It has been extensively documented that brown eggers have common egg color issues due to many factors but I have yet to see an Olive Egg with the same off color issues, it would be nice to see some White banded eggs and Calcium deposited on the outershell Olive eggs too.
For example White Banded Eggs:
Extra Calcium layer ontop of the brown will give a Purplish tint to the eggs
