Social media is abuzz with all things purple in Niagara Falls! In case you missed it, Niagara Falls was illuminated purple beginning at 10 p.m. last night for Queen Elizabeth's II 90th birthday. Purple is considered the British royal's official color.

Hours before the illumination, pop superstar, Prince, suddenly passed away and landmarks around the U.S. lit up purple in tribute to his global hit, Purple Rain.

See the video from last night's purple illumination below.
