The Tovero (also known as Tobero)[1] coloration is a mix of tobiano and overo colorations in Pinto horses and American Paint Horses. The genetics of pinto coloration are not always fully understood, and some horses have a combination of patterns that does not fit cleanly in either category.
Some characteristics of a Tovero colored horse include:
Dark pigmentation around the ears, sometimes called a "Medicine Hat" or a "War bonnet"
Dark pigmentation around the ears, expanding to cover the forehead and/or eyes.
Isolated "shield" dark markings completely surrounded by white, particularly on the face or chest.
