Experience
ColorK
A React Native app that consumes an API in Python to process any picture taken by the user and returns the most predominant colors found in the image. The user can select the number of colors they want to know about. The app provides the hexadecimal code for each color and allows the user to copy it. It also keeps a process history on the installed device because there's no user authentication. Developing this app was a personal project.
