Allowed range:

Appearance
Prismatic shimmer allows any part of the coat, including any markings and patterns, to fully or partially become any colour. Prismatic can alter the colour of anything, including eyes, horns and hooves.
Prismatic is genetically a combination of all three shimmer variations (Ruby, Jade and Sapphire), which means prismatic is allowed to be any colour found on both those palettes, as well as any colour inbetween. Prismatic shimmer can be saturated or desaturated, dark or light (pastel), as well as a mix of all.
If no markings or patterns are present then shimmer can not create patterns/markings on its own, it can only fully or partially(gradiented) colour the base coat.
Can optionally have a glittery effect on any area affected by shimmer. The glittery effect should have very small sparkles, not large individual stars or spots.
Shimmer can optionally affect mane/tail where it touches, or affect the mane and tail individually on its own. Can also cause dapples on the coat.
