Bridesmaid dresses with sparkly wedding dress

Hi everyone … first time posting on here! We are having a black tie wedding and my wedding dress has a sparkle/shimmer to it. Initially I was going to have champagne coloured bridesmaid dresses but now finding my dress we don’t think it will look great together as the undertones for mine are more silvery/cool tone sparkle. Any ideas on nice bridesmaid colours to complement my dress? At the moment I’m leaning towards black dresses but don’t want my bridesmaids to blend in too much with the crowd as I expect a few people will wear long black dresses
