Delta's added/adding mood lighting to many of its aircraft, and I got to see it in action in earnest on my last trip to DAB. On CMH-ATL (MD-88), the indirect lighting behind the bins was used and it wasn't too bad. ATL-DAB (757) saw it used briefly before being turned off.

DAB-ATL (another MD-88) saw the crew use both the indirect and sidewall lighting (all blue) and it was too much, almost bordering on irritating.

What do other FTers think of it so far? Has anyone seen colors other than blue?
