Using webcams to track gestures

Question

I wanted to develop a program that uses a webcam to track four colors and which will be on my index finger and the finger of my hands, and in accordance with the gestures of my hand, the computer will interpret these gestures and execute the command. For example, if I have a website open, all I have to do is hold my fingers and the web page will increase. I need a stackoverflow community advice on where to start and if I have any tips for me. Thanks in advance.
