No Way Out From the Lunatic Asylum

Nikon D810, 1/8 sec, f/9.0, 85mm, ISO 200

Here is one wall of windows in a building on the grounds of the Trans-Allegheny Lunatic Asylum. The outside of these windows are bluish in color (here). I am not sure why the windows are yellowish onto inside and bluish on the outside, but both make for compelling images.
