Rimmed is a marking that covers the extremities and 'rims' of a dinosaur.  This marking can have a hard edge or soft edge, but may never be fully blended.  This marking also cannot mimic other markings, but may have a chewed edge or create small patterns.

This marking can be lighter or darker than the base color.
This marking must be one solid color.
This marking cannot form large stripes or spots. (Small, textured edges or holes in the pattern are acceptable)
