Have orange lights on for a few weeks before Halloween this year, but other than that it’s just a day or 2. Red, white, and blue for July 4 and memorial day. Blue and white for the first BYU football game. Pastel colors for Easter. Red or pink for Valentine’s Day. Green for St Patrick’s. And my kids pick colors that they like for their birthdays. On New Year’s even I did a sparkle effect across most lights except for some on the garage section (same one pictured below) that do a fireworks animation.
