This is a simple Python microservice for color clustering using the K-Means algorithm. It is built using the Flask framework and is designed to be run using Docker.

The endpoint accepts a list of colors in hexadecimal format along with a dictionary of predefined categories and a threshold value. It then groups the provided colors into respective categories based on the minimum Euclidean distance and returns the clustered colors as a JSON response.
