Egg color from hybrid hens?

[Mrs. Mucket]

This is a genetic question--not sure if this is the right section for it: If a white-egg or green-egg laying hen is crossed with a brown-egg breed rooster, what color eggs will their "daughters" lay? Or is it a little of this and a little of that?

I have two hens who's mother was a brown egg layer (Orpington) and father was a green egg layer and one lays a brown egg, one lays a greenish egg.
I have almost the same mix (one different breed, Maran) and those hens lay a olive egg.

I was wondering what egg color you would get with a blue egg layer (Arucana) crossed with a dark brown egg layer (Maran)? different shade of olive?

 

[Mrs. Mucket]

You must have a beautiful assortment of eggs. Who needs dye for Easter eggs? Hopefully we'll be hatching some crosses out this spring so I guess we'll have some new colors next fall.

The brown egg trait is dominant so they will mostly lay brown eggs.

 

[Mrs. Mucket]

Ah so are egg color traits somewhat like eye color in humans?

a bit dark but this are yesterday's eggs

Assuming the birds are pure for egg color genes (except for green and olive which are produced by being heterozygous for two colors).

brown + white=brown
brown + blue=green
brown + green=1/2 brown, 1/2 green
brown + chocolate=dark brown
white + blue=light blue
white + green=half light blue, half brown
white + chocolate=??? (average brown?)
blue + green=half blue, half green
blue + chocolate=olive
green + chocolate=half olive, half dark brown

I'm 99% sure this is all correct. Feel free to correct me if any of them are wrong.

ETA: The ones in bold I'm 100% sure are correct.
