Hi there. Airy concrete will create more of a contrast with the floor, tie in your white cabinetry better and it will be easier to work with in an open plan.

I would actually ask you to consider Cloudburst concrete, the warmer tones will tie in better with your brown floor. https://www.caesarstone.com.au/colour/4011-cloudburst-concrete

Thank you so much, I really, really appreciate your response! I love the Cloudburst Concrete too, and hear what you are saying about adding some warmth, but could never convince my hubby to go with a benchtop that light.

You're welcome, if you want you could post here an image of the floor, I would always recommend testing samples in real life but I could take a look and give some feedback :)
