Hi there, I looked around and couldn't find anything, but how would I go about finding/outputting the (lets say 3) main colours in an image/video; similar to what iTunes does now with album art. I want to be able to automatically pull the main 3 colours and use that data to send to DMX/other lighting on stage

The average colour of an image can be easily obtained using jit.3m, but what you're asking is not a trivial task. I think you would have to implement it. I don't know if anyone has done it before but here is a very nice description of the problem and a valid strategy for its resolution in OpenCV:

And using Javascript (you can access the code on github):
