Happinow...if you intend to create a tropical, beachy,cottagy feel to your home here, white is the choice. If you plan to be more traditional or even a West Indies, tropical feel then medium is best. If you plan to have a very traditional, more formal feel than maybe darker would be best. Darker also lends itself to contemporary depending on the lines.
However...you can have beachy with dark and contemporary with all and ...It is a difficult question and all of the answers are RIGHT. Just don't change your mind into the process and have to pay the $250.
I didn't help, did I?
But.....the people who help you make choices are excellent, EXCELLENT, decorators and can guide you once they know what you want to create in your new home. (And they do NOT try to steer you toward the more expensive...)
Here's a hug.
