Duality in many of its forms is one of the leitmotives of modern (abstract) mathematics. In this talk we show how some general approaches to classical problems (such as 4-color theorem fame) and less classical (e.g. frequency assignement) coloring problems are related to a surprisingly rich spectrum of dualities and yield interesting results and problems.
