How can i tell the difference

[Bazzinator]

i paired up an opaline split lime cock to a lutino opaline hen in hope of getting a lutino lime opaline cockbird. i know what they can breed and they had five eggs all hatched out.
how can i tell the difference from the straight Opaline cock bird to the Lutino Lime Opaline Cock, as i have one of each, mature birds, and the difference between them is minimal

great help is required with these.

i wont be able to post photos as i recently broke my camera.

a young opaline cock will appear to be green with lots of yellow and red patches on it and i guess that the lutinolime opaline cock would be alot yellower.
also opaline cocks have dark flight feathers and a lutinolime opaline has white flight feathers
