Which theme should I use on my Christmas tree this year?

This is my first Christmas in charge of the decorations and I can't decide how to decorate. Everything will be decorated around the trees theme. I have a red kitchen, a beige living room and my house is very open. I can't decide if i want to do a multi colored tree that is fun and youthful (I'm 22), try to pull off a blue "snowy" decor or a more traditional one with red and cream. What do you think?
