This is a pretty crass statement to make. If the focus is full-on navigability, I agree that contrast in the navigation bar is paramount. Yet, for many sites with simplified features, the emotional experience trumps the direct navigability of the site itself.
This is especially true for sites like Airbnb (as in the example) where in addition to emotional response, there is an immediate focus on activating users. The focus shifts from full navigability (logging in, become a host, etc) to searching for a listing.
