How to spot violet gene in green budgies?

[erlabella]

Does anyone here know how to spot the violet gene in green budgies? I have a female green budgie who I think has the violet gene. Her coloration is a mix between light green and emerald green. She’s definitely an opaline. Her cheek patches are a bright indigo-violet colour, her tail feathers are a dark turquoise colour, and she has light blue feathers near her vent and tail. Does she sound like a green violet budgie?

Supposedly have no "ribbing" to the feathers that dark greens have (SF dark), so the feathers appear more satin like, tail feathers paler than navy blue in SF Dark, and no dark blue flight feathers.

What Monica posted is about the only way to VISIBLY "spot" it...I've seen some very dark, olive-green Budgies that I was sure carried the violet gene, but that's not how it turned out at all (I bred them for 20+ years). Usually, unless it's extremely obvious, which it usually isn't, you must either know their lineage and do the genetics to figure it out, or just know that you purchased one that carries the gene for breeding or expresses it...

The dark-violet face patches have nothing to do with it at all btw, as stated they typically have feathers of an entirely different "texture" or feel than other Budgies have, along with having no blue in their flight-feathers at all.
