White Spot (Bicolour):-
Bicolour is where there are areas of white on a coloured coat (or colour on a white coat), and is caused by the 'white spot' gene. The main coat colour is unaffected by the presence of this gene, and it should not be confused with the solid white coat colour. There are three types of 'bicolour': Bicolour, Harlequin and Van. These are described below:

Bicolour
Most of the coat is coloured, with patches/areas of white. These areas of colour/white should have well-defined borders and the white will cover 1/3 to 1/2 of the coat. The face should have a white blaze.

Harlequin
At least 2/3 of the coat is white, with the remainder being coloured, with well-defined borders between the different areas. The face should have a white blaze.

Van
Coat is white with patches of colour confined to the head and tail. One or two patches of colour on the body are allowable, but no more than this.

Mittens
If a cat has white feet, it is said to have mittens. Ideally, each mitten should be similar in appearance to the others, but often the white will extend further up one leg than the others, or will finish lower on one than on the others. Mittens are often accompanied by 'laces'; where the white extends up the back of the cat's leg, ending in a point. Indeed, 'laces' are even desirable in some breeds. Mittens are thought to be related to the white-spot gene in some way (although the exact nature of the link is unknown), so a cat that is Bicolour, Harlequin or Van will always be described as such, and not as mitted. For example, you never get a 'black mackerel tabby and white bicolour and white mitted', even if the bicolour includes white feet.
