For the past four nights, the Empire State Building has been lit up in rainbow colors- each side of the tower and antenna were different colored lights. The ESB website has a lighting schedule, but no explanation appeared for the colors other than that it was a "private lighting"- I'm so curious! You can apply to be a "lighting partner" and choose the colors for an evening (I'm dying to know what that costs!) but they allow you to choose a maximum of 3 colors. Hmm... there's also a rumor that it was lit in tie-dye for the band Further- led by former members of the Grateful Dead. Whatever it was for, it was definitely a pretty sight out my window the past few nights!
