The two genes affect coat color differently.
Dun washes out the coat while leaving the points (legs and head) mostly unaffected. It also adds dun factors or primitive markings, including shoulder barring, zebra stripes on the legs, prominent dorsal stripe, and cobwebbing on the face. Dun can affect any base coat color. Dun on bay is bay dun, dun on chestnut is red dun, dun on black is grullo, etc.
Buckskin is quite simply a bay horse with one cream gene. Cream dilutes the body color relatively evenly. Buckskin is to bay as palomino is to chestnut.
