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?

There are several companies such as AGL, Johnson, Baba, Kalinga etc that makes engineered quartz in India. The choices of colors they offer also quite extensive. The prices of these quartz are not that much higher than good quality granite. So visit one of these showrooms to get a touch and feel of these materials.

I have white granite countertops. Kindly suggest care for spots or stains

Are you referring to Nano white crystallised glass also known as nano white marble as it replicates the look/shine of good quality white marble. Thanks, Nitin CORNERSTONE DESIGNS Bangalore
