Magical gene / ground and strong white

Galaxy

A black field over most of the horse with the coat left showing in a few lobed patches, and the black full of stars - hard points and long curved streaks in white and a cool accent or two.

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.

Wild pair	Shows as	How often
`Gxy/Gxy`	Galaxy	0.001% — 1 in 100,000
`Gxy/n`	Galaxy	0.019% — 1 in 5,263
`n/n`	Wild type	99.98%

The file

common/src/main/resources/horsegenetics/genes/galaxy.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.

Galaxy

Black lies over seven to nine tenths of the horse - head, neck, barrel, hindquarter and the upper legs - and the coat survives only as a handful of irregular lobed patches, hard-edged, mostly on the lower legs, the belly, and parts of the shoulder and hip. Two kinds of star sit in the black. Point stars are small hard circles, scattered unevenly, densest over the barrel and hindquarter and sparse on the legs. Streak stars are long tapering strokes curved along their length, following the body's contours - front to back on the barrel, up and down on the shoulder and hip - and they cluster near the shoulder, the crest and the hindquarter. Both come in white and in one to three cool accent hues. The mane and tail are black too and carry the same two forms, the streaks running with the fall of the hair.
