I am trying to work out if the colours I am picking for my new kitchen all match. I don't have a lot of experience in interior design so am wanting some advice on whether the tones work together.

We have decided on WK Quantum Quartz Naturale Concrete for benchtop and splashback, and Polytec Blossom White cabinets (still undecided on Matt or Sheen finish - have heard the Matt surface is more work to maintain/keep clean). Floorboards are a light oak colour.

I am still yet to pick a paint colour but am thinking either Dulux Natural White or Dulux Snowy Mountains Quarter on walls with Vivid White on arcatraves and ceiling.

Do these colours all match? Any suggestions for white paint colours? Would you go Matt or Sheen on the cabients? It is a small townhouse with north facing windows but there is a double storey home quite close next door so no direct sunlight comes through. It's quite small so we want to keep the colours light to open up the space as much as possible.

Any help would be greatly appreciated!
