The Colorpoint (cs, cb, cm) and Albinism (c) genes all share the same gene locus.
Colorpoint is a heat-sensitive gene, where the expression of color is concentrated on areas of the body that are generally colder: the face, ears, legs and tail. The set of these areas is commonly referred to as the points of a cat, and always show the cat's original color to it's full expression. The body of the cat lightens depending on which colorpoint gene is acting primarily.
Siamese point (cs) creates high contrast between the body and the points.
Burmese point (cb) creates low contrast between the body and the points.
Tonkinese point, where the cat expresses both siamese and burmese points, creates a medium contrast between the body and the points.
Mocha point (cm) is a bit more of a wild card, per ToE standards. While in real life, the contrast of a cat with the Mocha gene depends on it's combination with siamese or burmese points, in ToE you can freely choose how much contrast is expressed between the body and the points, and the general color for Mocha.
Albinism, on the other hand, removes all pigment from a cat's coat.
For all colorpoints:
The border between the points and the body can be hard-edged, soft-edged or fully blended. However, all points should show the same edge. This means that you can't fully blend the face but leave the legs hard-edged.
The only exception to this would be if white spotting cuts through the points.
The body can be, optionally, one solid color. This would hide all markings that would otherwise show on the body. If you are choosing to still show body markings, they should be lightened to a contrast corresponding with the colorpoint genes.
If choosing a solid colored body, it can feature subtle darker gradients along the spine, or lighter gradients along the belly.
Points for the legs should be roughly the same height. You shouldn't have really low points on the hind legs and really high points on the front legs, or viceversa.

While Siamese, Tonkinese and Burmese are all colorpoints, the distinction between them is how much the body is lightened.

While a cat with regular points (siamese, tonkinese or burmese) will remain its original color, a cat with mocha points will turn brown or tan alongside the classic colorpoint coloration.
Mocha Points are often dull, rather than bright colored.
Since mocha affects both red and black bases, torties should be designed with two different shades of mocha.
While mocha can make a cat look tan, the lighter colors are often reserved for dilute mocha.

Albinism, in cats, will create a cat that is entirely white due to the lack of pigment. It's possible that some of the skin color shows through in the sensitive spots where the fur tends to be thinner. Due to the lack of pigment, albino cats are the only ones allowed to have naturally red, blue or lilac eyes.
Albino eye colors should remain fairly light and dull, rather than dark or too pigmented.
