Magical gene / colour modifiers
Gamma
Two to four diffuse fields of light on the barrel and flank, each with an outer bloom falling away to nothing, their colour sweeping along the horse rather than sitting in patches.

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 10,000 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 |
|---|---|---|
Gam/Gam | Gamma | 0.0005% — 1 in 200,000 |
Gam/n | Gamma | 0.0095% — 1 in 10,526 |
n/n | Wild type | 99.99% |

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.
Gamma
Two to four diffuse fields of colour a foot or two across, on the barrel and the back of the flank, gradient at every margin and hard-edged at none of them. The hue is not one colour: it sweeps along the horse, so a field near the shoulder and a field near the hip are different colours and the change between them is continuous. Each field carries an outer bloom a few inches past its own edge at a third of its core saturation, falling to nothing. That bloom is what makes it read as light rather than as paint.
