It would be interesting to play around with multiple different geographies, perhaps comparing the Honolulu color wheel to that of a research station in Antarctica over the same time period. Might it be possible to identify a location just by looking at its pixel almanac?
I also wondered if, instead of looking at many random users' photos, what if the program analyzed images from one person's daily life? If we omit the messy details about location, objects and people in the images, distilling everything down to pixel colors, would patterns start to emerge? Might it be possible to look at a person's color almanac from last year and gain insights into their daily experiences?
