Modifiers

Color Modifiers

Modifiers alter the appearance of the base coat but do not dilute it.

Flaxen (F)

Flaxen is a recessive modifier that lightens the mane and tail of chestnut horses. Depending on expression, flaxen can range from a slightly lighter mane and tail to a nearly white mane and tail.

Inheritance

Because flaxen is recessive, a horse must inherit a flaxen allele from both parents in order to visually express it.

Expression

Flaxen only affects chestnut horses. Bay and black horses may carry flaxen but will not visually express it.

Silver (Z)

Silver is a dominant modifier that affects black pigment. It lightens the mane and tail while having no effect on red pigment.

Inheritance

Only one copy of silver is required for expression.

Expression

Chestnut horses may carry silver but will not visually express it because they do not produce black pigment.

Sooty

 (Sty)

Sooty is a dominant modifier that adds dark hairs throughout the coatcoat. andExpression can darkenrange from subtle dark shading to heavy darkening across the topline, shoulders, andentire body.

Inheritance

Only one copy is required for expression.

Expression

Sooty can affect nearly any colour.

Examples:

• Bay → Sooty Bay
• Palomino → Sooty Palomino
• Buckskin → Sooty Buckskin
• BayChestnut → DarkLiver BayChestnut

Progressive Modifiers

These genes affect how a horse changes over time.

Gray (G)

Gray causes a horse to gradually lose pigment as it ages.

A gray horse is born its original colour and slowly lightens over time.

Examples:

• Bay → Gray
• Black → Gray
• Chestnut → Gray
• Palomino → Gray

A gray horse still genetically remains its original colour underneath the graying process.

In EquestriCraft

Gray progresses through multiple visual stages:

1. Foal Coat
2. Early Gray
3. Dapple Gray
4. Advanced Gray
5. Fleabitten/White Gray

The exact progression may vary from horse to horse.
