Stres-reduction an airport

Does serenity adds security? BWI (Baltimore Washington International Airport) will be rolling out the first of its kind pilot program for stress reduction in specific airport screening areas. I think this is a fabulous idea, as airports (especially post 9-11) are extremely stressful places. Racing to catch a plane, stuck in lines that move at a snails pace, then jostling to strip off all offending articles of clothing and accessories at the screening area, etc. I find myself much more anxious and short-tempered in airports.
This is a description of the special screening area:
Mauve, blue and purple panels of lights glow, low decibel ambient 'spa' music hums, and smiling employees offer quiet greetings and assistance.
But if these images from TSA's promo video are any indication of what is to come, I'm not sure how "soothed" I'll feel!
TSA planners have been tinkering for months in a warehouse at Ronald Reagan Washington National Airport, testing these new aspects "You can actually influence some behavior subliminally through color," said Catherine Lillie, head of the checkpoint-testing team. source

Coming from a profession where the psychological effects of color is basic knowledge, I have to chuckle at her seeming incredulity over the idea.

What do you think of the concept?
