If you think you're looking at color palettes of different shades of brownish gray, you're not exactly wrong. I'm sure people would love to paint their bathroom Roman Rotunda Slate or some made up name like that. But it's not that simple. You're actually looking at the seasons—spring, summer, fall and winter—and you just don't know it.
Shin Seung Back and Kim Yong Hun combined one million pictures of each season using photos one million pictures from Flickr tagged spring, summer, fall and winter. Each picture filled up a pixel (with the dominant color of that picture actually filling the pixel) and you have one million pixels showing you what the season looked like.
It's kind of funny how all the colors of the pictures just blend together to create something that doesn't look like what we expect it to look like. I like that. Though fall owns the lovely brown, yellow and decaying hues, every other season looks like static. But that's because when we see a small version of the pixels, everything blends together. Getting up close, it reveals more details like blue streaks, green tint and white backgrounds.
That's Spring above.
This is summer
I love fall
Winter is coming
