Do you have a theme or color palette for your Christmas tree?

Mine is a very simple tree with white lights, gold balls, and metal dragonflies. I love it. Next year I'm thinking about doing a paper theme, and making ornaments out of old book pages.

My parents tree was decorated by my little sister, so it's got multi-color lights, blue lights, and purple lights. It's covered in every single kind of tinsel you can buy, and then every color of balls with some candy canes and straw wreaths thrown in for good measure. My sister claims it's an 80's disco theme, but she wasn't even alive in the 80's so I'm not sure where she's getting that from.

What's your tree theme?
