I would paint it the color of those other cabinets not far from it. Right now, it really stands out because its so dark. You dont need any other colors mixed in there.

I'd paint it the blue you are using in the room.

Paint it the color of all your other cabinets and trim.

I think it would be nice to introduce a shot of color, so I'd go with a color of blue that coordinates with the other blues you have in the house. Nothing too bold, you want a softer blue.
