The Siamese cat is a popular oriental breed across the world and that are renowned for their distinctive colour points, which contrast with their white or cream bodies.
The colour points themselves come in a range of different shades, and this is reflected in the Siamese cat’s breed standard, which has expanded over time to encompass new shades and variations of the colour points. Not all of the possible colour point combinations that Siamese cats can be seen in are officially recognised by all registries, however-the original Siamese colour was seal point, and over time the blue, lilac and chocolate shades became accepted too. Now, Siamese cats can be seen with red points, tortie points and other variants too-but the one thing that unites all Siamese cats is the fact that they have darker points on the tail, face and legs, with a light body.
However, the Siamese cat’s colouring and points originates from a certain colour gene called the Himalayan gene, which is a black colour that expresses in the Siamese with a partial albino variant, and that ultimately, led to the breed’s appearance and colouration as we know it today.

That said, you occasionally hear mention of all-black Siamese cats, or Siamese-type cats with all black coats, which poses the question of whether or not a pedigree Siamese cat can actually be all black in colour.
Essentially, a seal point Siamese cat is genetically a black cat, although they are not black in colour due to the partial expression of the albinism trait. This is because the seal point colour is actually black, although it often appears to be dark brown rather than pure black.
If you see a cat whose fur is all black but otherwise looks Siamese, you are probably looking at an Oriental cat, which is a large, striking oriental breed with similar features to the Siamese. Another option is the Havana cat, which carries the black gene expressed as a dark brown or black.
