First of all it is not ugly. Second, Sharon Craig came and spoke at our guild, twice in fact. her theory is, use for sashing, whatever color you want the quilt to be. So, if you are interested in blue, use blue, if you like the lighter softer look, go with the white. i didn't look, but do you have any other colors in your fabrics, like maybe green? Lay the blocks on green, and see what happens.
