Show bar chart of colors in sample images

[egrace479]

Display the distribution of colors in the sample image(s) in a bar chart.
Potential packages to do this are colordistance (R package, so likely would require translation, used by the butterfly group). May also be able to use phenopype (python package, not currently used by butterfly group, but potential).

Looks like this would require translating colordistance to Python--doable, but not urgent.
