If the actual colors are fairly represented online, I worry that the two fabrics are so different from one another.
If that's the case (and seeing as how you have 3 yards of each), I'd consider doing a One Block Wonder (OBW). I think the two fabrics have just enough color in common that you could organize the resulting blocks into a stunning display where you transition from the one color scheme to the other.
Of course, be sure to find a place on the quilt to show each of the original fabrics - borders, backing, etc.
Good luck!
