I just messed around by saving the picture to paint program and fiddling with the custom colors.
I love the furniture, very cute. I think I'd try to go with a bluish color to make the furniture pop, I'm thinking contrasting colors instead of complimentary colors ( I don't like the blues I made) or I like the greens too... Of course paint samples once you get the furniture home and in your light will be MUCH better to judge by but this is fun in the mean time.
I would go with a simple comforter and let the furniture stand out. But that's just me and I have rather simple tastes.
This must be so exciting!!! I'd love to get to redecorate!
