Painting the Green Room...Blue?

Rachel enlisted Ben and I to come and help paint at the Newson's house.  The 'Green Room' is a big room with a beautiful book shelf/library, Nedra's office and Ron's TV nook.  It has been a dark green color since the Newson's moved in 25+ years ago and they decided to brighten it up a bit by painting it a lighter color (soft blue-ish). 

 

The only problem... the Green Room is no longer Green! hum...?
