Skewbald is a term often used as a generic reference to colour to describe a horse of any colour, except black, with the overo or tobiano pattern or both (tovero).

The amount of white and coloured patches can vary immensely and the patterning on each horse is unique. The coloured patches can be any colour other than black eg bay, buckskin, dun, chestnut, brown, grey, palomino, etc. As bay, dun and buckskin horses have a black mane, tail and lower legs their skewbald versions often show 3 colours (their main body colour, black in the mane, tail or lower legs and white) and some refer to these horses as a Tri-Colour.
