I have an image of a flower cluster with some “pop” to the color. The background is fairly neutral / uninteresting. It occurred to me that the cluster in full color transitioning to monochrome might be interesting. I can think of a way to attempt it in an image processing app. Can it be done in PL/NiK/FP? What I want to do is see the results in real time, not iterative cut, try, cut, retry, “wash, rinse, repeat”.
I realize this is a “describe purple to a blind person” situation, but think of an object in color, in the middle of the frame, becoming less and less saturated, until all color is lost, while going further away from the center of the colored area.
