Not having seen the piece, I can believe the color. Looks yellow/orange but maybe that's the true color of the wood. Did you set set a custom white balance for the lights?
Is the inside of the bowl black on one side or does it need some light? You can often use a piece of white paper or cardboard to reflect some soft light where needed.
This picture John Lucas posted once shows a piece of white paper on the left.
I'm not a big fan of black backgrounds but prefer a neutral color background with some soft shadows. I think that shows the shapes better. This is a personal preference, however.
