I'm goofy because for me it depends on the breed for what colors I like.
Arabians: fleabitten grey, black, bay, bay sabino, and chestnut (must be dark chestnut or bay though)
Thoroughbreds: dapple grey, dark bay, dark chestnut with thick blaze and leg markings
QH: dark dapple buckskin, grullo, red dun, palomino,double dilute, dunskin, dunalino (no white or very very little)
Paint: black with any pinto markings (really love sabino and splash), dark bay tobiano, dark bay sabino
Minis: leopard appy (any color spots though LOVE black), black pinto (any pattern though love splash and sabino), double dilute, palomino, dapple buckskin, silver buckskin, silver dapple, deep chestnut, deep bay
Gypsies: black tobiano, bay tobiano, buckskin with thick blaze and leg markings, silver dapple.
Yeah I'm a bit odd, but most definitely quality over color
