Create Most Often field

Hi PBINewbie920 ,

Please try these measures:

Primary Color % = 
VAR _customer = MAX('Table'[Customer])
VAR _color = MAX('Table'[Color])
VAR _count =
    CALCULATE (
        COUNT ( 'Table'[Customer] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Customer] = _customer
                && 'Table'[Color] = _color
        )
    )
VAR _count_all =
    CALCULATE (
        COUNT ( 'Table'[Customer] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Customer] = _customer )
    )
VAR _rate =
    DIVIDE ( _count, _count_all )
RETURN
    _rate

Filter = 
VAR _max = MAXX(ALLEXCEPT('Table','Table'[Customer]),[Primary Color %])
VAR _result = IF([Primary Color %]=_max,1)
RETURN
_result
