Extract all vivid colored pixels from the image (Saturation (0.15, 1], PB (0.18, 0.95)), partition the overall image hue into a band, then sort by overall image perceived brightness (simple sum of all pixels/number of pixels).
Seems to work better - I'm calling this good enough for now. (Potential improvement - classify very dark and very light images in separate bands (start and end?))

, PB(0.18, 0.95)
), partition the overall image hue into a band, then sort by overall image perceived brightness (simple sum of all pixels/number of pixels).Question: best way to extract overall image hue?
