225 South 6th Street is....pink?

Here is an odd discovery.  For the last several hours, 225 South 6th Street a.k.a. Capella Tower has been glowing pink.  Normal, the crown on top of the building glows a vibrant cool white.  The only time I've seen this color is when the HID lights are warming up.  Is this intentional? 225 South 6th Pink
