That one sure looks like it's going green.
Likely, but then the whole photo is green due to poor white balance setting on the camera. If we can assume the slat board should be white, you can get the idea. Fluorescent lights are on the greenish side of the spectrum, so correcting with white balance control on the camera can counteract that.
That said, the clear coat over Rickenbacker Silver often goes yellowish, lending a greenish cast.
