I have. I have gone for beige walls and beige quartz countertop. my kitchen will get ready in a week's time. I shall then post pictures and seek feedback from the experts on houzz.com.

Hi Anurag, Black counter top is very common and you can go for ample combinations like light and dark grey, yellow , red, green ...and their combinations will look great. So no need to worry..go for any colorful combinations. Regards, Sujoy

Please post the image of the kitchen...

Thanks. I am aware of potential materials (e.g. quartz). I was looking more at what color combination works well with ash oak cabinet colors? Would a softer tone mimicking wooden countertop (e.g. brown/beige colors) work better or would a darker tone such as black/dark brown go well?
