Chimera creates a patch of coat that expresses a different genotype than the rest of the horse.
(Above example is a Chestnut with Palomino Tabard Chimera)

Chimera expresses as an irregular patch or blotch of color, and should not resemble any other marking.
Symmetrical, uniform, or intentional-looking markings (such as stripes, skulls, patterns, symbols, etc) cannot be made with Chimera.
Chimera should have crisp, clear outlines; edges should not be blurry or gradients.

Chimera may present in up to three "patches", and may not cover more than half of a horse.

Chimera markings may not overlap or interact with Somatic - no more than 3 base colors may appear on any horse.

• Coat: May be affected by the chimera color.
• Mane and Tail: May be affected by the chimera color.
• Skin: May be affected by the chimera color.
• Eyes: May be affected by the chimera color.
• Hooves: May be affected by the chimera color.

Range:

• Minimum: May be hidden entirely.
• Maximum: Up to half of the horse covered by no more than 3 patches of Chimera.

Chimera Colors:

• On Foals: May be any color genetically possible from the parents (excluding anomalies that the parents do not have).
• On Imports: May be any color achieved by removing genes from the import genotype or changing the base color (e/a). May not have any genes that the import does not have.
