Yea, that still leaves the question: what color? When you are really stuck, sometimes a little outside help can be just the thing. MyColortopia has two fun online tools to help you narrow it down. My Image Inspiration helps you pull a color palette from a favorite photo. In my case I picked an snapshot I took on my last trip to London and let it suggest a few shades.
