You might not have a choice. I recently had a new build. The frame is pale yellow with silver script and the crank was spec'd out to be Ultegra. The LBS decided that the gray wouldn't look nice with the pale yellow (and, of course, he was absolutely right). When the first crank was defective and he had to get a replacement, he said he had a hard time finding the silver version. I'm glad he did the extra legwork...the gray wouldn't have looked right with the silver script and other components. Of course, that was a triple--it may be easier to find a double in silver.
