Winning Colors (1988) is the only roan to win the Derby.

Genetically WC is grey. The roan gene doesn't exist in the breed. If they lighten w/age, they are grey and she's white now.
"Grey" in a horse is a progressive "conditition" effecting color. Roan is permanent. What does exist in the TB is rabicano which (similar to roan, but different genetically) is a sprinkling of white hairs over the primary body coat. In a rabicano, like a roan the white does not progress and become more prominent.
