A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

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?

Laminate is incredibly durable. Currently we have a stone-look gloss surface with tiny, occasional pits for texture, no problems with food particles getting stuck. Previously we had a matte finish in color, it lasted 20 years before looking scuffed. I would not use raised texture on a counter bc the peaks would wear more quickly.

Hey, You can always go with high gloss grey and white laminate which is a very standard combination. I suggest you look at century or merino catalogues or visit the nearest store as you can feel the finishes and have a clear idea of what you're getting into.
