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?

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

Which is the best wholesale markets?

It all depends on the budget you are looking at. As an architect i would give preference to granite over quartz any day. If your budget is INR 150-300 per sqft then go for south indian granites and if your budget is INR 500-1200 per sqft then go for Imported granite (Suggestions : Bianco Antico (in white), Blue Pearl (in dark blue-dark grey tone), Baltic brown : light+dark brown combination). As far as Kalinga quartz or any other brand quartz is concerned i find it not at all value for money, you'd end up spending INR 500+ sqft on something which is still in its experiment stage in India. The company is spending money on marketing and PR thats why new architects would promptly suggest quartz. I have heard enough complaints from home owners about quartz discoloration and bending. Fun fact : there is no warranty on any defects arising in quartz due to usage, which explains even the manufacturer of quartz dont want to take the responsibility of there own product. Reach me out if you need color advice for countertops. Thanks :)
