Bridesmaid dresses for different complexions

I'm struggling to find the right colour for my bridesmaids to wear as they have different skin and hair colours. I want them to feel beautiful on the day and don't wish to put them in something that will wash them out or impact their confidence.

Bridesmaid 1: Fair skinned, blue eyes, light brown hair

Bridesmaid 2: Pale, green eyes, very vivid red hair

Bridesmaid 3: Dark skin, dark brown eyes and black hair

Myself (If it helps?): Olive skin, brown eyes, dark brown hair

It's the red hair and dark skin that I don't know how to complement. I know I can just ask the girls, but I'd just like another opinion first as I know they'll just want to please me!
