Black stainless is a thin coating on top of regular stainless steel. It is prone to scratching. It also differs from one manufacturer to another. So, in a couple of years, you'll have ugly scratched appliances, and when you look at replacing some of them, you won't be able to find anything that matches unless you stick with the same brand -- and assuming that this particular brand hasn't already discontinued their line of black stainless appliances.

I'd stay clear of black stainless unless you are furnishing a low-budged rental unit and really don't care much either way. On the other hand, regular stainless steel is fine. It is relatively easy to maintain. Scratches can be buffed out, if you are sufficiently determined (and skilled!). And it's likely to be a mainstay of all brands for many years to come. Mixing'n'matching of brands is generally not a problem with stainless steel either.

If your budget isn't constrained, then other options would be either to buy panel-ready appliances or to have your appliances ordered in custom powder-coated finishes. The latter can be perfectly color matched ... but while it looks amazing, that service comes at a price.

yes! it totally works, grays, blacks, stainless all goes very well together

Black stainless!!!!

Agree with M on black stainless scratching. When choosing appliances for a kitchen, we had more than one salesman (in different stores) tell us this was a problem with black stainless.
