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).

The average of 0° and 359° is obviously 359.5°.

it's a radial scale.

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.

You know what, I completely agree.

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.
