Which color wingtip is the best/most versatile with various shades of blue denim (dark to light)?

[skinny]

Trying to decide what color wingtip to get for dressing up my various jeans (all blue from dark to med-light) and can't decide which color will work best with the various denim AND shirts/jackets. Any advice and recommendations? Looking at the below for example, which color do you think is the most versatile? Black, merlot, or walnut?
