[PD] color tracking in Gem/Pd-extended?

Wondering the best solution for color tracking in Pd-extended. I'd like my solution to be cross-platform so that rules out PDP and friends. All I've come up with is to use [pix_blob] to track the color, and to try to minimize the tracking color in the background. There's probably a Gem object

How will you avoid gating the color of the object you're trying to track as well? To use your method below I'd suggest using some combination of [separator] and [pix_background] to create a mask so that [pix_blob] (or the color gate, depending on the setup) only affects new objects introduced
