I purposely made sure my bridesmaids stood out. I'm having them wear a mix-match neutral palette and did not tell anyone but the bridesmaids. Knowing my FH's family, they are so stuck on bridesmaids wearing ONE color, therefore that will be the official wedding color, which means they can all wear that color.
I told FH's family (and our mothers) that the colors are mauve - that way they can all be "uniform"with a family color and my bridesmaids can still stick out and be "bridesmaids". I feel uncomfortable having certain family members think they're wearing the same colors as the bridesmaids and having people confuse them as part of my bridal party.
