I personally would add some color somewhere just because I am not a huge black and white fan. I would audition some colors and see how you feel about it. Maybe refrain from really bright colors and try for teal, sunflower yellow, or a grey-blue? I was in a challenge at my LQS one time where we had to pick a line of fabric out of a basket. I ended up with a line that had only grey, black and light taupe in it. Absolutely not my style at all so I introduced a blue and it really made the quilt stand out. I won second place
