: "For the band of the same name see Skewbald (band)"Skewbald is a color pattern of horse. A skewbald horse has a coat made up of chestnut (or any color besides black) and white patches, on top of either pink or dark skin. Other than colour, it is similar in appearance to the piebald pattern. Some animals also exhibit colouration of the irises of the eye that match the surrounding skin (blue eyes for white skin, brown for dark). The underlying genetic cause is related to a condition known as leucism.

In British English usage, skewbald and piebald (black and white) are together known as "coloured". In North American English, the term for all large spotted colouring is pinto, with the specialized term "paint" referring specifically to a breed of horse with American Quarter Horse or Thoroughbred bloodlines in addition to being spotted, whereas "pinto" refers to a spotted horse of any breed. Americans usually describe the colour shade of a pinto literally: black and white, chestnut (or sorrel and white, or bay and white.)

Skewbald horses which are bay and white (bay is a reddish-brown colour with black mane and tail) are sometimes called tricoloured.

Genetically, a skewbald horse begins with a chestnut base coat colour (called "red" by geneticists), or some other set of colour genes other than black. Then the horse has an allele for one of three basic spotting patterns overlaying the base colour. The most common coloured spotting pattern is called tobiano, and is a dominant gene. Tobiano creates spots that are large and rounded, usually with a somewhat vertical orientation, with white that usually crosses the back of the horse, white on the legs, with the head mostly dark. Two less common spotting genes are the overo gene, that creates a mostly dark, jagged spotting with a horizontal orientation, white on the head, but dark or minimally marked legs. The sabino pattern can be very minimal, usually adding white that runs up the legs onto the belly or flanks, with "lacy" or roaning at the edge of the white, plus white on the head that either extendings past the eye, over the chin, or both. The genetics of overo and sabino are not yet fully understood, but they have recessive characteristics and can appear in the offspring of two solid-coloured parents, whereas a tobiano must always have at least one tobiano parent.
