Beyonce honored Prince during opening night of her Formation World Tour. During a costume change, a box structure on the stage turned purple, as the speakers blared "Purple Rain." This gesture called back to when Beyonce and Prince sang a Purple Rain medley during the 2004 Grammy Awards. So between that, and Beyonce's thanks ("Prince, thank you for your beautiful music"), her simple tribute spoke volumes, even though she didn't say much. Watch both moments below.
