Update from 2015:
This variety sure sports a lot, as I’ve noticed lots of variegated/mosaic types do. Reminds me of Fingerpaint, but a warmer color or “autumn” version of it. One thing I’ve observed about the sporting mosaic (Fingerpaint, Twist and Twirl, etc.) is that they will sport to a solid, but I haven’t noticed those sports revert back to a variegated/mosaic.

Parentage might be Fairway Mosaic or Splish Splash or maybe even a Mosaic Kong. Dark red stains on yellow leaves really looks like dried blood. Really.
