Alternating colours for BAR Graph with single measure

Since you have ties in your ranking, the Rank calculation has to break it first. I created the following ranking measure and used it in your CF measure. The file is attached below my signature.

Rank = 
VAR __customernamerank =
    ADDCOLUMNS (
        ALLSELECTED ( Customers[Customer Name] ),
        "RankCust",
            RANKX (
                ALLSELECTED ( Customers[Customer Name]),
                CALCULATE ( MAX ( Customers[Customer Name] ) )
            )
    )
VAR __maxcust =
    MAXX ( __customernamerank, [RankCust] )
VAR __customerrank =
    ADDCOLUMNS (
        __customernamerank,
        "Rank",
            RANKX ( __customernamerank, [Sales Amount] * __maxcust + [RankCust] )
    )
RETURN
IF( 
    HASONEVALUE(Customers[Customer Name]),
    MAXX(FILTER(__customerrank,Customers[Customer Name] = MAX(Customers[Customer Name])),[Rank])
)
