Does hue make sense at all? If yes, you could calculate the vector mean (convert degrees to x and y axis, average, and convert back to degrees) and get something sensible out of that.
But good question, if it makes sense at all. Since hue is not a linear scale, the average is not exactly the ‘middle’ of anything. At best you could interpret it as the poster being somewhat biased in that direction, but ultimately you could have a poster with no green at all, which still averages out to green, and that just doesn’t feel right.
A more complex graph, which shows the frequency of the colours used, might be more useful…

Ah yeah, good idea.
