color_isolation.py is a Python program leveraging OpenCV and its HSV filtering capabilities to color isolate a specific part of a picture.

Here are the consecutive process steps:

1. The user executes the program and the HSV version of the input picture appears
2. The user clicks 5 times on several places on the object he wants to color isolate. This step allows to record samples of HSV values
3. Based on these values, an average of the HSV values will be elaborated and the HSV range is computed
4. Using the HSV range and the cv2.inRange function, the mask isolating the object of interest is created
5. Using the same mask, the region of the object of interest is black-outed from a grayscaled version of the input picture and the original colored object is added at this precise location

• Tested on macOS Big Sur version 11.0.1
