This data visualization provided by Sven Carlsson (@svenaxel_) and created by Martin Bellander reports the colors used in 88,000 oil paintings since the 1800s. The source for the underlying data is based on a BBC database of paintings. The beauty of this visualization is how striking the increased prevalence of blues and reds in paintings are.
After discovering this initial color map, with some research I found some other great ones to share. This blog post by Theodore Gray (@WolframResearch), the co-founder of Wolfram Research, explains the clustering program he wrote to group and map the colors from the Lion King. As he explains in the blog:
You can clearly see the shifting moods. Take a look, for example, at the ending (ignoring the long expanse of nearly solid black, which is the credits). You see strong, violent reds and yellows: That’s the climactic battle scene between Scar and the returning Simba, come to reclaim his father’s throne (it’s Hamlet with lions). Then things are bad, bad, bad: It’s dark, it’s raining, the pride lands are ruined, the black of night descends literally, figuratively, and in the color map. And then the sun rises on Pride Rock! Bright blues and greens burst out, the new king holds his son up to the sky, and we’re off to the credits!
As if the Lion King visual wasn't striking enough, they went on to combine all 75 Disney Animated movies into this amazing graphic.
