Magical gene / fields and regions

Iuari

Concentrated patches a shade off the coat, each one ringed by a scatter of bright speckles that thins as it moves away.

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 833 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.

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.

Iuari

Patches that read as deliberate focal points rather than as marks: darker than the coat on some horses and lighter on others, concentrated on the neck, shoulder, barrel and hindquarter and carrying on down the legs, with soft indistinct middles. What names the marking is the rim - each patch is outlined by speckling that crowds at its boundary and thins away from it, so the patch looks lit from the edge. It goes under white markings rather than over them, and the whole horse still carries its ordinary speckling as well.

  1. the patches themselves — PATCHES, painted with TINT
  2. speckling crowded at the patch rims — SPECKLE × PATCHES × PATCHES inverted, painted with TOWARD
