palette Common Persian Colors
Solid White
Classic Persian white longhair — dominant white or high-grade spotting can produce this look.
Silver Shaded
Shimmering white undercoat with fine tipping — inhibitor gene expression.
Calicos & Torties
Black, red, and white mosaics — X-linked orange gene, almost always female.
Dilutes (Blue-Cream)
Pastel blue and cream patches — dilute path of tortie genetics.
dns Persian Coat Genetics
- 1
The Polygenes Factor
Unlike short-haired breeds, Persians rely on multiple genes to maintain their distinctive ultra-long 'peaked' coat texture.
- 2
The Dilute Gene (d/d)
Recessive dilution turns Black into Blue and Red into Cream. Both parents must carry the gene to produce dilute kittens.
- 3
Bicolor Masking
Advanced genetic alert
High-grade white spotting can mask the cat's underlying tabby pattern, often appearing as 'ghost markings' in kittens.
