In my opinion, one of the best ways to transform a table setting is a table runner. It is a quick way to help you tie in your color theme, especially if you happen to change that theme every week. With little expense invested, you can choose to go more vibrant with the fabric and leave the solids to the plates so that you can reuse for year-round events. I picked up this Black & White fabric from a local fabric store for under $5 dollars a yard, and I only needed a yard and a half for my 4 top table! Since this was a more casual setting I folded my edges under, however, if you wanted to go more elegant you could serge the edge of the fabric to give a complete look.
