chroma.average wrong computation

[marcelpi]

Hi,

I was just trying to average the red, green, blue primaries using chroma.average and I was expecting the result to be [120, 1, 1]. Instead I got [116.57, 1, 1].

Red hue = 0
Green hue = 120
Blue hue = 240

So, I was expecting the average hue to be (0 + 120 + 240) / 3 = 360 / 3 = 120.

Am I missing something here?
