The dark blue appears almost black in my picture, and it's best seen in the flesh. Also, my iphone pictures don't show the colours so well 
Perhaps a slightly less dark blue, with dark blue stitches, might be a better shade of blue? My 1815 has a slightly less dark shade of blue (more navy than cobalt blue), which I've tried to accentuate by placing against a light backdrop. I think this shade of blue may be more what you had in mind perhaps for the RDM. Cheers!
