When it comes to kitchen sinks, there aren't too many design choices. Usually the options are stainless steel or a porcelain farmhouse style sink- if you want to go a little crazier, there's also the possibility of concrete, copper or pricey granite. But now designer Jonathan Adler offers another choice- big, bold, color. In a limited edition collaboration with Kohler, Adler has designed kitchen sinks in bright, cheery colors including Greenwich Green, Picadilly Yellow, Palermo Blue and Annapolis Navy. The sinks are made from enameled cast iron and would look equally cool in the bathroom.
