Description

A guide made to help understand how Roan works in Celtic Warlanders. Below are simple rules to make designing a little easier:

☘️ All roans have the distinctive 'landmark' on their front legs being the inverted V.
☘️ Roans vary in shade, from dark to pale but a heterozygous horse will never have as pronounced colouring as a homozygous.
☘️ Roan in celtic warlanders can cover the cheeks and go across the forehead & nose.
☘️ Roan does not change the skin colour.

☘️ Corn spots - Caused most often by injuries, the hair re-drows no longer having the pigment which results in a spotty appearance. Not hereditary.
☘️ Partial roan - Roan that's not as evenly spread, some areas are more pigmented while others 'ran out of ink'.
☘️ Roan dapples - They appear as reverse dapples, ranging from faint to pronounced.
☘️ Blaschko lines - When the foal/fetus is developping the cells are carried down certain paths. Most commonly down the ribs pigmentation can leave a leftover of those paths resulting in a unique birthmark.

☘️ Homozygous roan will always be quite pronounced but can appear in all the variations listed in the visual guide above.
☘️ Homozygous roan can cause skewing (brindle-like stripes cutting through roan). They are never as pronounced in coverage as true brindles.

☘️ Roan vanishes when the winter coat grows, it only shows on the summer coat!

Foal accuracy:
☘️ Foals are not born showing roan. They grow into over multiple sheds.
☘️ Roan appears around the first shedding (6 months).
