A "bright red comb, face or wattles" would be a DQ. So if it was close to or bordering on looking red it would be DQ'd. Otherwise the color is supposed to be "deep mulberry" to "deep mulberry, approaching black." As for losing points: not specified, but if a judge felt it was too light he could simple DQ. He or she would be looking to place birds with darker combs higher, all other things being equal.
