     Greg_Deckler's measure will only return 1 in subtoatl. Please try this code to create a measure.

    Desired Count = 
VAR __ADD =
    ADDCOLUMNS (
        'Table',
        "Count",
            VAR _COUNTBYID =
                CALCULATE ( COUNTROWS ( 'Table' ), ALLEXCEPT ( 'Table', 'Table'[articleID] ) )
            RETURN
                SWITCH ( TRUE (), [Tag] = "Pink" && _COUNTBYID > 1, BLANK (), 1 )
    )
RETURN
    SUMX ( __ADD, [Count] )

    Result is as below.
