Your color scheme is an excellent starting point for planning all of the elements of your event.
An analogous color scheme is a color scheme using colors adjacent on the color wheel. A great example would be to use reds, purples and blues. Analogous color schemes are both unexpected as well as naturally easy on the eye.
