Sedan and Coupe use two different blues. The Sedan is Royal Blue Pearl, which is very dark. The Coupe uses Belize Blue Pearl, which to my knowledge is not on any other Honda or Acura Vehicle. Would have to see it in person to make final judgement. I don't like the dark blue on the sedan (I wish Cool Blue Metalic carried over from 2007), but I think the brighter blue will look good on the coupe. I believe that San Marino Red is a carryover color and it is a quintesential coupe color. But, I'd hate to see myself coming and going even more than buying and Accord already does for us.... so, I'd go with Belize Blue if I were shopping a Coupe.
