Roger Asked :

Is the Onyx finish for Clearwater Sienna a solid white? I am looking for an undermount kitchen sink in a composite that is a solid white or maybe ivory.

Answered By QS Team Answered by the QS Technical Team

Onyx is a metallic black finish. Polar would be the white finish for that sink. It’s not a ‘pure solid’ white as it’s a granite finish, but it’s the closest to solid white we can get.
