    The problem is that averaging hue makes no sense at all because hue is not a longest scale.

    If you take a red poster (0) and a blue poster (240), it averages to green. Or take red (0) and red (359), averaging to cyan (180).

        By that logic, the average of red and cyan is both purple and lime. Still useless.

          Not if there is a clear trend. If most movie posters are blue, three average will be blue.

          But i agree, it is useless if there is no clear trend.

        I wouldn’t trust someone who tried to visualize hue like this to make that calculation correctly.

      It would have made more sense if they had shown the distribution of hue as a polar graph and just had one every decade to show how it changes over time.
