Unsupervised learning is applied to a data set of randomly generated colors. The red, green, and blue values are used as features to categorize each color under a specific parent category.
For example, purple might be categories as Red or Blue. Likewise, Sky Blue would be categorized under Blue.
The following graphs show the results of clustering and categorizing colors by their red, green, and blue values.
