High contrast wireframes - why that way? If the team will be iterating (and gawking) at these assets repeatedly over time, then give their eyes and head a break by keeping the colors inverted: light wires on dark background. Just like many apps/products that do this already, this method also allows for any color accents to really pop - such as the primary CTAs and tap zone indicators. As a bonus, these wires are closer to traditional blueprints, which helps keep focus anchored to the logic, value exchanges and flow instead of visual design or fit&finish.
