Studies done amazingly enough by LIRR in the late 90's show greys, blues were preferred. So we move forward, and we concentrate on comfort (and avoiding crazy colors), and things that make the trip easier. Easy ability to plug in both laptops and phones / tablets (people tend to bring their own entertainment), super reliable wifi with decent speed and capacity, good work tables and good ability to nap, noise absorbance, decent info signs on where you are, speed, what's next. Hand holds on aisles. Good, clean bathrooms. Far better food options outside first class. And due some consumer tests before locking down designs.
