My reference sheet! Artwork by  Goldenrod Original submission is here.

Basic rules:
- Color transitions have jigsaw puzzle theme, but still have standard attributes (e.g. the transitions are still furry in organic pics)
- Only the eye-patch has a defined shape (same as the color references), otherwise the jigsaw juts can be applied freely
- The ear tips and top of the tail are the darkest shade
- The eye-patch and ear-fluff are a different shade from the rest
- There is an undefined discoloration on the feet simply called "the brown thing," it is not a pad, artists can pick the shape
- Should I be transformed the colors do not need to be preserved if it doesn't make sense for the new form, but the jigsaw theme and eye-patch do
