Genetic origin and mechanism
One Cream variant in SLC45A2 dilutes red pigment on an e/e base. Palomino is therefore not an independent base color.
Development and variations
The golden shade may lighten in winter or sunlight, and the mane and tail may yellow or whiten over time.
Possible confusions
It may resemble flaxen chestnut, gold champagne or some pearl phenotypes. Genetic testing may be needed.
