My wife always has a color scheme for her tree each year for Christmas... yes, we get his and her trees.  Mine has no scheme.  Gaudy is the word for that.

This year, my wife has a red and white tree, which turned out very lovely this year.  My one contribution; one green light in the midst of red and white that adorn the tree.  It drives her crazy but it's my way of letting her know that I love her.

Merry Christmas Honey
