A bicolor dog or cat has how many coat colors?

A bicolor dog or cat has two distinct coat colors. This term is used to describe an animal that features two different colors in its fur, which can appear in various patterns and combinations. For example, a bicolor cat might have white fur with patches of black, or a dog might exhibit a blend of brown and white. The definition relies on the presence of these two distinct colors rather than additional hues or shades, making two the defining number for bicolor animals. Other options suggest a different number of colors, which does not fit the accepted definition of bicolor in animal coat classifications.
