Sinosauropteryx prima, a small dinosaur known from a fossil preserved so well we know what color it was (a sort of rust red on the back, white on the belly and a banded tail). It was also the first non-avian dinosaur found with direct evidence of feather-like structures.
I didn't have red tissue paper so I had to go with purple lol.
It's my second design that implements color changes, and the first one that makes a pattern instead of having one solid color change. Of course, it's not something really complex, but it uses up a lot more paper than I expected.
Folded and designed by me from a single uncut (and crudely homemade) 30cm square of double tissue foil (which was a bit too small but still worked).
