Sunburnt Modifier  -  ns / ss 

Because its a gene that is somewhat affected by the sun - in low light conditions, the pinkness is less/almost gone, but in harsh sunlight the horse will develop bright pink/red tones. 

No one knows how the gene started but they have deemed a mutated gene because the hairs in the soft parts are somewhat translucent.  Its not very sought after for ACHs that need to be out in the sun working all the time,  because the chance of melanoma is rather high. Thankfully there is sweatproof sunscreen. 

​

-- Pink skin in the tender soft spots of the horse.

-- tones can be from bright pink to light red. 

-- Most commonly on the Chest & Groin, but also on the Nose, nape/chin area, as well. 

-- overlays all other mutations, except somatic/chimera types. 

-- the blue gene tends to make the colors more vibrant, but its not always the case.
