Bridal party colors - bridesmaid dresses and groomsmen

Hi there!! My bridesmaids are wearing mismatched dusty rose and desert rose. The groom is wear gray suit with blue vest with a blue tie and hint of pink
The groom did not want the boys wearing suits (sigh) - they only think he really requested during the wedding planning so they are wearing blue vest and pants only…..what color ties should they wear? Would wearing any shades of pink like blush/Dusty rose be too much?
