Grey is a color modifier and no horse is born grey. Grey begins to modify the birth coat color sometimes months or even years later. They will begin showing signs of grey around the eyes, flank and below the elbow. Grey patches occasionally will develop on the body, croup, or thigh before they are visible around the eyes. Grey is progressive and aging causes the coat colors of grey horses to progressively lighten to almost white. Dappling is common and often, older grey horses show speckles of their original coat color hair and are called “flea-bitten.” A grey horse must have at least one grey parent. Ideally to preserve the true color of the horse “Grey” should be added to the birth color black/grey, chestnut/ grey, palomino/grey etc.
