Mixed pinto patterns is when a pony has more than one pinto pattern. A tobiano that is also an overo (splash or sabino) is called a tovero. Tobiano sabinos are extremely common in Chincoteagues. Any combinations of the pinto patterns is possible, it is possible for a pony to carry all of them. Some patterns can visually hide each other so it can be difficult to visually tell if a pony is mixed pattern by looking at it. The expression of multiple pinto patterns can result in unusual looking patterns and markings.
A badger face resembles a blaze in reverse, the blaze is dark instead of white. Badger faces are the result of multiple pinto patterns.
