In the discussion for a BSA to influence breeds (https://forums.dragcave.net/topic/183688-bsa-to-influence-breed/) the question came up about ways to influence color for breeds in which the dragon's color is left to random chance, such as Dorsals, Gemshards, Nebulas, Striped dragons from a Striped x Striped pairing, and others. Possibly also included are alts for Blacks, Dark Greens, and Undines. The suggestion doesn't seem to fit very well with the breed-influencing BSA, but it might work well
