You can't go wrong with white.... your wood trim in the house is white, toilets and sinks white, right? It will all look coordinated.
Black can be striking.... I've used it with light cabs and dark... and even white woodwork like I mentioned above. Trick is, you must take everything into account when using it..... and color balance it to countertops, hardware, flooring, etc. to make it wonderful.
MORE than most guys want to bother with. I mean... it's a refrigerator, right!
Bottom line, white is the easiest to keep clean. Does that do it?
