The pointed pattern is a result of the partial albinism gene. This point restricted pattern came about from a genetic mutation that is responsible for producing the enzymes that produce pigment. When this mutated enzyme is subjected to temperatures above 98°F (37°C), the cells of the hair root will produce little or no pigment for the growing hair. The neck and the body of the cat are warmer and don't develop any pigment. Thus, their point color is restricted to the areas of the body that are cooler, such as the extremities (face, ears, legs, and tail). There also several "modifying" genes that can further affect the color and density of the points.
	A Siamese that is overweight tends to be darker because the extra layer of fat insulates the skin from the body, thus causing it to produce more pigment. Kittens are white when they are born because the temperature inside the womb is very warm. Color can also vary with each individual cat. Anything that affects the temperature of the Siamese can also affect their point color. A Siamese that has been ill will often show "ticking", or lighter colored hairs in it's mask because the actively growing hairs will be un-pigmented in the elevated temperature of a fever.
The blue eye color of a Siamese is also due to the partial albinism gene. Siamese have little to no pigment (yellow-brown) in their eyes and the blue color is actually a result of reflected white light from the retina. This is called Tyndall's phenomenon. The eye color can range from a pale china-blue to a deep blue-violet.
Siamese darken as they age, so ages are given for each of these cats' photos so the difference can be seen between kittens and adults. At Fairy Dust Cattery, I show in The Cat Fanciers' Association exclusively, so I am only showing examples of the four accepted Siamese colors for CFA. Other associations accept more colors for Siamese. In CFA, seal point, chocolate point, blue point, and lilac point are the standard colors. See CFA's Siamese breed standard.
