Magical gene / spots and rings

Glow

Small glowing speckles crowded along the topline, with the hooves lit to match. Every lit part of the horse shares one colour.

What it can come out as

Glow	`Gl/Gl` · `Gl/n`
Wild type	`n/n`

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 2,500 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
`Gl/Gl`	Glow	0.002% — 1 in 50,000
`Gl/n`	Glow	0.038% — 1 in 2,632
`n/n`	Wild type	99.96%

The file

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

Key	`horsegenetics.glow`
Phase	magical — it adds signed colour in phase 3, after the pigment has resolved
Priority	301 — where it sits in the one `(priority, key)` paint order
Alleles	`Gl` · `n`
Varies per horse	3 values drawn once off the expressing allele copy, so a foal that inherits the copy inherits the look
Built from	AXIS, SPOTS, TOWARD, emissive

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.

Glow

Fine luminescent speckles densest over the neck, shoulder, ribcage and hindquarter and thinning toward the belly, with all four hooves lit in the same colour. One hue per horse, with the speckles a shade paler than the hooves. The mane and tail are untouched.

speckles down the upper body — SPOTS × AXIS, painted with TOWARD, and it glows
lit hooves in the same colour — AXIS, painted with TOWARD, and it glows

Wild type

No glow.

Paints nothing.
