The term 'Colorful Equine' can be solved by the four-letter word 'Roan'. Roan is a coat color of horses, characterized by an even mixture of white and dark hairs on the body, while the head and points (lower legs, mane, and tail) are darker than the rest of the coat. Roan horses often have a mottled skin, particularly around the eyes and muzzle. Roan is a dominant gene, meaning that only one parent needs to carry the gene for it to be expressed in the offspring.
