The colour is Beauti-Tone's "Über Luxe", but I've been using Behr's Paint & Primer in One, so it's a colour match off their swatch. It's a medium taupe-brown.
On my sample board it looks like this (taller board on the left):
It looks much darker on the wall because this hallway gets no direct (natural) light.
The green (Behr's "Olivine - Google image turns up several photos of this shade) from the above photo will be the living room colour, and the lighter grey will be the office colour.
