I'd love to see the end result!!

I think a deeper neutral tone would work nicely and really make the window and door trims stand out. Also look nice with the black pendant light.

I would definitely ditch the brown marble and go similar to the window sill. It is just beautiful. It looks like Carerra but you can find similar tiles that are from Chinese quarries. Marry it with white paint and add white and grey tones to your accessories. You could accent it with any color as it is a neutral. Brown dates very quickly where is white marble is timeless and classy. Good luck!!

We recently renovated my son's kitchen/ family room in a weekend. His oven needed replacing so it was a good opportunity to 'fix' it all. We rang around and got quotes on having the cupboard doors professionally painted but it was way too expensive so we took the pine laminate cupboard doors off and painted with a white laminate paint and replaced all the timber handles with chrome ones. We retiled with 600x 300 white marble look tiles (leftovers from our bathroom) (cut the old tiles out and re-sheeted the walls so we had a good surface to tile on) and repainted ceilings and walls. Replaced a dark timber venetian blind with a see through 'sun-out' blind and painted all the architraves white (previously mission brown). A new mixer tap replaced very ancient 'double' taps. We were totally shattered at the end of the weekend, but the kitchen looks a million dollars and the room looks twice the size now the pine and mission brown have gone. We are pretty chuffed with the result achieved by us unprofessionals!
