You’re right Rob. The question is a bit general so i apologize. What I’d like to be able to do is anaylize the hues of a given image and export hat data into a table that I can then import into Open Music. I found a similar thread " target="_blank">here and the idea around jit.rgb2hsl looks promising.
I think part of my generality is because I waiting to see what the results are going to be. That will determine to some extent what I will do with the info. To clarify though I am not looking for the frequency of say Light Blue. Perhaps a better way to look at it is to think of anaylizing the entire blue spectrum.
