It's hard to see the shade from the photo but black and white always create a nice contrast. The crisper the white the better the worktop will look. Here's an example of one of ours:

I think the stone cupboards would be fine with the dark worktops, I agree with the previous comment that it will create a darker feel, so I think that you should keep the walls light and fresh

We have installed Howdens Stone on a number of occasions and it is a really neutral palate for a wide range of colours!! So I say go for it!!

thanks so much to all for taking the time to respond, I feel reassured and will definitely go for it. :)

Hi There.

It depends on the look you are going for?

But think the colours you have chosen work well!

thanks for comments. Unfortunately not even close to having the end result, I had to choose these before agreeing contract with builder for new build, it has been delayed while we await building warrant. We have finally got the go ahead and hope that it will start in the next couple of weeks. Most likely be next year before I have any results to show :(

Have you thought about 'grey' for your cabinetry. We mix our own colours but have a look at Farrow & Ball colours, perhaps Purbeck Stone, which looks very smart with black granite. Perhaps have a look at our profile for some inspiration.

@Jones1987 not sure if you've looked recently but there's loads of new ranges in Howdens and an abundance of different greys. If you're worried about aftersales with howdens,there's no need,they can replace/send things out to you within a day or two,anything that isn't used at the install can be returned for a refund
