Gosh I'd never say I hate a colour! From a clients point of view I love them all, even if I don't like it I'd never tell a her that, I want people to make their own choices. I put the colours in front of them, we talk about what they want or what vision they have and then I'll guide them, even if its a colour I'd never wear.
As you say Andrea colours look different on different people and I'm convinced we all see colours slightly differently too.
