Species mimicry in corporate logos

The logos of the fast-food joints on a stretch of desolate American road reveals a kind of species mimicry, or evolutionary convergence:

Notice how all of these companies use shades of red and yellow in their logos? One might argue that Waffle House doesn't really have red, but their buildings have red trim just below the roofline. I couldn't find the logo for the L'il Cricket convenience stores (no website), but their logo is also yellow and red. One other one not visible from the photo above, but with the same color scheme is Pizza Hut…
