I can not decide on a substrate of my tank, help?

This is what I currently have: 15 pounds http://i275.photobucket.com/albums/jj293/irtreefrog/DSCN2021.jpg white sand, five pounds of black rainbow gravel and 1.2 pounds of gravel. Also I will be adding about 4 plants. I want to change to either sand all black, all Dark blue sand, all sand brown, black or sand mixed with 5 pounds 10 pounds of sand in dark blue. I can not decide what I want, but … The sand is not difficult cleaning … my vacuum is not fine gravel with him.

I think all black or brown, all look better. I have to think the fish are happier with colors natural. Most fish are more color and more relaxed if kept on a dark substrate.
