I concur wholeheartedly! She's a very pretty opaline lime green cinnamon recessive pied!
You can tell she's an opaline because the body colour seeps into the wing feathers creating a parabola-shaped area of diluted or absent markings. For recessive pieds, it can be kind of tricky to discern opaline markings from normal ones since the amount head stripes vary from budgie to budgie.
Telling which colour she is is fairly simple, she's a lime/light green because there are no dark factors and just looks lighter than a budgie with one or two dark factors (dark green and olive green respectively).
You can tell she's a cinnamon because the wing and head markings are brown and she doesn't have red eyes (which eliminates fallow and lacewing).
Recessive pieds are relatively easy to identify. They have mostly yellow or white feathers with body colour usually only found on the rump and lower belly. Sometimes they have lots of wing markings, other times they have very little or none. Recessive pieds always have dark eyes with no iris rings, no matter how old they are.
That's pretty much all there is to it. I hope I helped!
