Above is a link to a thread on BYC about Opal OEGB. Very cool birds. Looks like in 2013 they were accepted as a new variety of OEGB. Congratulations. That thread has pictures AND -- a painting by Ron Smith. A very different look from the one we are aiming for, I believe.... we are going for lavender + the cream hackles + the color I'm going to call peach on the wing triangle...and maybe even another more saturated but dilute color on the shoulder of the male's wings.
For female -- the pale pink breast, lavender barring markings on tail and hackles and the cream colored hackles IMO.... quite different from the Opal OEGB coloration.
Henk particpated in that Opal thread and helps determine it is a different gene from lavender.
Yes, opal is a different gene from lavender and a different coloration from what you are going for.
