The purply/brown ee egg layer sounds like it carries brown at least, and maybe no blue. and probably won't change to lay green, the colour they start is the colour they should stay (although they can get lighter and darker but the base colour generally stays roughly the same).

If the other is a green layer, with brown and blue: if that one is brown/brown blue/blue and you put with blue/blue (like your legbar) you will get blue-green, because the one brown passed from the ee will turn the blue to a green in the offspring.
if it is brown/0 blue/blue you could get blue or green (because you may or may not donate the brown, but will donate blue)
if it is brown/brown blue/0 you should get only green (because 1 brown gets donated)
if it's brown/O blue/O you would get blue or green.... (you may or may not donated the brown or the blue, or both, or neither)

if you take a green layer, and breed to brown egg line rooster you get darker green (more olive, but not quite olive). if you take green and breed to blue then you get lighter green-more to the blue-green side.
if you take blue and breed to brown (assuming they have 2 copies of the genes) you get green.
If you take blue and breed to DARK DARK brown (like a marans) you get more olive.
if you take a green and add more brown it gets more green.....oh, i said that already.....but taking a green to a green will not give you the same shade of green because the green is really a blue painted over by brown, and there isn't just one brown gene, there's lots, so it might not be the same gene, so you may end up painting more brown over the blue....
Kathy, ok now my head hurts..lol.. :running-chicken:

I found this picture online and was going to test it out to see how accurate it really is. The dull spearmint looks cool/different.
But the question will be which colour of eggs represents the male and/or female for the experiment?

Problem is you never know what colour the boys would lay if they were girls.....you can predict the first generation (ie marans x marans should be dark brown) and then that boy with blue would give a boy with dark green.....but cross that kid with blue.....um.....any male off that breeding could be lighter green or blue....and you cant really know until you hatch the next generation and fit those pullets colours jnto the chart and work backwards to figure out dad.....

Also, blue plus brown will not give you all green layers. Some will lay (or sire) green, some brown. If you're using Ameraucanas for the blue half, and a single combed breed for the brown half, as a general rule any offspring with a pea comb has the blue egg gene, so it's easy to tell which rooster to pick for the next generation. Legbars carry the genes for blue eggs in different spots that Auracanas/Ameraucanas, so I have no idea what the distribution would be in the offspring, and which rooster carries what colour genes could be a crapshoot.
