I use agreeable grey a lot because it goes so well with other colors - great choice!

I love the Coral Rose as well, but here is both a blue and a green option.

Scanda SW6529

Green Onyx SW9128

As for accents - using dark grey with pops of the accent color (different shades of it) will tie everything together. Ex: If you go with the Coral Rose - Think of a dark grey tray for the vanity with coral pink soaps, coral candle and some greenery in it. The dark grey tray may be metal or even an antiqued glass.

Hope that helps inspire you!

I was also thinking of doing a wood accent wall, but my family is concerned that wood walls are going out of style. As a pro, I trust your judgement in trends, what's your intake?

Personally I LOVE wood accent walls. I believe that with your home you should do what makes you happy in your space. If you are not planning on a move in the next 2-3 years then I think you shouldn't worry much about figuring out what will be in style and go with your heart. It is not like we are talking about something like a kitchen cabinet that is hugely expensive to change. Professionally I think the wood walls will be around for a while because a lot of people like the warm cozy feeling they give....(disclaimer: no designer has a crystal ball!)

Thank you for the advice! It will be very helpful!
