Simple Color Tracker with oF

Hi everyone!
I’m quite new to oF and also to coding (please bear with me haha)… Currently I’m trying to write a program, that uses my webcam as input and tracks only red and blue values to which I then want to draw a simple circle onto the position. I have checked a lot of sources but haven’t really found much for oF.
Does anyone know a simple color tracking example or an approach for how to do this?

Thanks in advance!
