Color detection and recognition

So a while back, I published a python package. ColorDetect is the name.
What this package does is to enable the user to get the most dominant colors in an image, starting with five by default, together with the percentage. It then has the ability to write this onto the image. As an example:
out_hex

So what do you think about this package and/or what new capabilities could be added to this?
