One of the nice surprises we had after moving to New York was that we have a nice view of the Empire State Building from our upstairs window. Not only that, but it was nice to discover that the colors of the lights on the building change fairly often. Most days, it is its signature white color, but for other occasions, they switch it up a bit.
For example, for the New York Rangers opening game night, it was colored in Rangers colors - Red, White, and Blue. For Thanksgiving, it was fall colors. This one is my favorite so far, Christmas colors between Christmas and New Years:
Sometimes the colors are weird. Like on Christmas Eve, it was half Christmas colors and half Hanukkah. Which means that it didn't really look good either way.
