You could try BM Queen Anne Pink.

Or if you want to go really pale, BM Old Country

These are more historic "pinks" / blushes than pink.

While this thread talks about nursery use, it does illustrate some lovely pinks that might get you in the right direction. I'd think that a pink that leans toward the yellow side would be more adult than a brighter bluish one.

Here is a link that might be useful: Pink?

I used Farrow and Ball Pink Ground in my living room. Love it. Looks different in all lights but very pretty.

My daughter's nursery is in the link Annie posted. I love that color for a baby (BM Elephant Pink), but if it were for a guest room or an older child, I would have gone with BM Gentle Butterfly.

Not BM or SW, I know, but Farrow and Ball's Middleton Pink is a beautiful, subtle pink.

We recently painted our powder room in Ben Moore Soft Sand. Subtle, grown-up pink.

when you look up "pink ikat" on google you get some very grown up ideas.
