Tristan is an unusual color. I've always labeled him as "bay roan" for the purposes of Coggins tests, stall cards, and shorthand discussions but the truth is that there's probably something else going on, genetically. He has a few quirks that don't fit the typical mold for a roan horse.
Sometime soon I'll do a whole post about his colors and his interesting points - yes, I promise, this blog will be about something other than endless rehab updates! - but in the meantime, I've been sucked into this blog recently, both for the gorgeous pictures and for the really intelligent discussion of color genetics.

Maybe when I put my picture collection together, I'll email them to her and see what she thinks.
