Just a silly suggestion for a cosmetic pearl that adds a texture overlay, so you keep the same colors except now your dragon has a glorious fluffy coat of fur or feathers.
There could be a fur-based pearl and a feather-based pearl, separately, or just one "pearl of fluffiness" based on whatever the developers prefer.
Bonus: For Zygovo, it would make the dragon extra fluffy, like a tiny chickadee in winter. Think feathers poofing out until the zygovo looks like a ball.
This is just a silly suggestion, something that might be fun/cute for some and wouldn't be a priority since it affects nothing but cosmetics.
Lorewise you could either explain this as a mutation to the dragon's scales, particularly a feathered variant, or you could say for a furred variant that the dragon has grown symbiotic hair-like moss over its body.
