When I bought these, I had originally thought that you could set them to white. You can't. However, I have a gorgeous "tree" that I bought last Christmas that has all the colors of the lights. I'll be saving these for the holidays and have ordered a simple set of plain white for the rest of the year. The lights change from blue to red to yellow to fuchsia to green - all the lights in the tree. These solar lights will be AMAZING at Christmas. I know they're not FOR Christmas but how amazing will these be shining in the snow?
