Using Unsupervised Learning Algorithms to Make Differential Groups?

The algorithm is unlikely to pick three shades of green that are all very close together. It kind of makes a compromise about where to ploy its limited colors by trying to have a broad coverage. So if anybody wants to do a pull quote and have your name, this is a famous unsupervised learning algorithm. We could say a muted colors and uninteresting by lindetran, what's your quote here?
