That all sounds lovely Sarah! I love the colours too. Our dining room has an archway to our kitchen & when we decorated it I wanted a cadbury purple, so I painted one wall in the dining room & one wall in the kitchen with the purple & the other 3 walls in each room magnolia to stop it being really dark. I've got loads of purple accessories too & I love it

I suppose it depends on how much wall you will have showing & what colour your cupbards & worktops/upstand will be as to how dark it will look when done xx
