Terri, I'm torn about a third color the two color quilts work really well and that leaves you the option of a third color for sashing. If I were to choose a third color I personally wouldn't choose white I think that would take it to a very "patriotic quilt" unless that is what you were wanting, and I wouldn't choose one of the blues in the print, to me that print is so graphic you don't want to muddy the look w/ the same color, I would choose black as the third color, keeps it graphic, black and brights always makes the brights pop.
