How about a crisp white or perhaps a grey color? I'm afraid your space will feel dark unless you keep it lighter, but I can't see how much light you get in the room.

Thank you. I was thinking I needed to keep it light was just concerned that the dark sink might stand out too much, but you are right as there really isn't a ton of light.

I think because the sink is small and doesn't cover the whole vanity top, you might be fine with white.
