Le Le is often mistaken by his new friends for a Siamese cat because of his little black face of coal digging. Black face, black legs and black tail, this seems to be the image of the Siamese cat in everyone's mind, but in fact, this is just a genetic type of cat, not unique to the Siamese cat.
Accent color, essentially a partial albinism variant, is the result of mutations in the body that promote the precipitation of melanin and the production of tyrosinase. The mutated tyrosinase does not work at normal body temperature and is active in places where the skin temperature is low, so the face, tail, and extremities far from the heart will be darker, and the winter will be darker than the summer.
There are many cat breeds with accent color genes, and the following are common.
