Colors of the Empire State Building

After a sunset shoot the other night, I came upon a beautiful view of the Empire State Building nestled between the buildings in Herald Square. There's actually a Twitter account which explains the reasons for the various color schemes on any given night. It read: "Tonight's colors: From bottom tier, green, blue, yellow sparkle (Finals weekend at the @usopen) #NewYork #NewYorkCity #NYC"  

Camera details: This was taken handheld at 1/80, f4, ISO 5000 on the OMD E-M10.
