I need help! I can't decide which sink I should get for my kitchen: copper or Silgranit (in dark brown or biscuit).

My cabinets are cream with brown antique/glaze finish.

My plumbing fixtures are all Oil Rubbed Bronze Grohe.

Granite counter tops are neutral: cream/browns/ some black

I have some stainless steel being used, Viking Cooktop and Viking double oven. But otherwise, the rest of the kitchen is cream cabinets since the dishwasher and fridge/freezer are paneled. Floors are dark drown distressed walnut.

I have to decide asap or my GC will kill me. Any advice please?????
