There's been a number of yellow/purple/grey/black strains coming in on indo pucks the last year and a half or so. Hence, all the stratocaster morphs we're seeing. I have some that are similar to yours, I'll grab pics if you're interested.
I took these off a maricultured puck about 12 months ago. Lots of interesting morphs coming through. Lemon heads and Simpson donuts are other named ones.
