Magical gene / spots and rings

Aurorae

Light in the ends of the mane and tail, brightening toward the tips - and nothing at all on the coat.

How each one is actually drawn - region by region, and the layers it is built from - is on the coding tab.

Finding one

About 1 in 5,000 wild horses is born showing this. That is the whole of the supply: catch one, or make one with the carrot below. Breeds set their own pools and a breed built around this gene will carry it far more often than the wild population does.

The file

common/src/main/resources/horsegenetics/genes/aurorae.json — a data-driven gene, not a Java class. It is listed in the index.json beside it and registered by Genes' class initialiser at startup.

What it paints

Each outcome, described the way the gene file describes it, and then the layers that draw it in the order they are painted. The prose is the part a reader checks a bake against; the list underneath is what the engine actually did.

Aurorae

The light is in the hair and nowhere else: the lower half or third of the mane and of the tail take it, brightening the whole way to the ends, and the coat itself is untouched. One copy lights the tips alone; two carry it further up the strands and brighter. How far up varies from horse to horse, and the boundary is a fade rather than a line - there is nothing on this marking you could put a finger on.
