no, i'm mean the buff IS shown under ascob, here's an excerpt from the standard

"Color and Markings
Black Variety--Solid color black to include black with tan points. The black should be jet; shadings of brown or liver in the coat are not desirable. A small amount of white on the chest and/or throat is allowed; white in any other location shall disqualify.

Any Solid Color Other than Black (ASCOB)--Any solid color other than black, ranging from lightest cream to darkest red, including brown and brown with tan points. The color shall be of a uniform shade, but lighter color of the feathering is permissible. A small amount of white on the chest and/or throat is allowed; white in any other location shall disqualify.

Parti-Color Variety--Two or more solid, well broken colors, one of which must be white; black and white, red and white (the red may range from lightest cream to darkest red), brown and white, and roans, to include any such color combination with tan points. It is preferable that the tan markings be located in the same pattern as for the tan points in the Black and ASCOB varieties. Roans are classified as parti-colors and may be of any of the usual roaning patterns. Primary color which is ninety percent (90%) or more shall disqualify."
