Data is Beautiful is a fascinating subreddit described as: A place for visual representations of data: Graphs, charts, maps, etc.
To create color analysis graphs like these, anvaka wrote a script to do the following:
Took color of each pixel in the image, made L component (i.e., Lightness) of the HSL color space as X coordinate, Y coordinate corresponds to number of pixels with given L value. Used interpolation function to move pixels from their original position to the destination over randomly assigned number of frames. [source]
For those unfamiliar HSL colors take three values:
– Hue is a degree on the color wheel; 0 (or 360) is red, 120 is green, 240 is blue. Numbers in between reflect different shades.
– Saturation is a percentage value; 100% is the full colour.
– Lightness (used above) is also a percentage; 0% is dark (black), 100% is light (white), and 50% is the average.
This gives a very wide spectrum of available colors and tones. [source]
