Pangare or Mealy Modifier – Horse Coat Colors

Pangare or Mealy HorseA few weeks ago I decided to give my colors section an update – it was time for an upgrade. There is some new info and the rest is quite simply better than it was.

Modifiers

There is an array of modifying genes which can affect base colors as well as each other, they can be further affected by dilutions and white patterns. Today I want to share a little about the pangare or mealy modifier which is commonly found in almost all breeds. This modifier is also found in other equines like mules and burros who are rarely found without it.

Seal Bay or Brown Base – Horse Coat Colors

Seal brown horse grazing
There are four base horse coat colors, black, chestnut, bay and brown. Black, bay and brown coats are caused by the agouti gene and it is the Dominant agouti allele that causes black hairs to be restricted to the points.

Agouti Magic

Seal brown can be subtle and is easily confused with dark bay, especially when there is a pangare modifier involved. Some registries do not consider it a different color, but a shade of bay.

Brown Comparison

Below is a couple comparisons of two animals that are similar in color, but different genetically. In both cases the brown animal is on the right.

Seal Brown Characteristics

The only physical way to visually identify a seal brown animal is the varying degrees of lighter, reddish hair found on their soft spots, including muzzle, flank, elbow and belly.

Basic Chestnut – Horse Coat Colors

Chestnut HorsesRecently I’ve begun updating the images in my colors section and getting in touch with the times when it comes to color. It’s a complicated ride, but it sure is a pretty one!

Basic Colors

Coloring in horses comes from a pigment called melanin which appears in two forms, eumelanin (black) and phaeomelanin (red). These two expressions are responsible for the two base horse colors, black and chestnut. All other coat colors come from an interaction between these two genes and that of various modifiers, dilutions and white patterns.
