Amerock recently added 2 new finishes, Polished Nickel and Gunmetal, to some of their popular collections. 

Gunmetal Finish

Gunmetal has a dark gray or blackish color. It is both ageless and contemporary.

Here's a great example of kitchen that uses Gun Metal finish cabinet hardware in their kitchen.

Polished Nickel Finish

Polished nickel is a contemporary finish that goes well with stainless steel appliances. It does not overwhelm a room which makes it a perfect fit in many surroundings.
