Color Labels in Photoshop

Question

Does anyone know if there is a way to change color labels WITHIN photoshop? i do NOT mean labelling a layer or group. I mean labelling a FILE within psd that can be read in Bridge/Lightroom. I know I can tag them there, but I would like to be able to open a group of image, retouch them, then add something in a script that changes the color label to, for example, green, so that when it shows in Bridge/Lightroom, it will automatically show the new color tag.
when you changea color label in Bridge, it has to resave the file completely (which can be an issue with bandwidth for those of us with small servers, not to mention sometime like dropbox or creative cloud which has to constantly upload an entire file each time). If I can add it to the script WITHIN photoshop, it will be a big timesaver too. Same thing with Lightroom - you have to manually SAVE the color tag into the file. I can see it in the File Info of photoshop (it is under ADVANCED).
And for that matter, is there a way to batch script other functions of the File Info, like changing star ratings? it doesn't seem to let me do that either

Answer 1

imagine you could use the marquee tool or a selecting-brush to drag or brush over some background elements, weeds in a field, Mountains, Buildings, Skies, etc.. adding the selected colors & patterns to the number of colors & objects to be removed..
then use the same brush to brush over colors & elements you want to keep, and the values for those colors are stored separately, even if some of the values are the same
then, you drag a brush around the object you want to remove from the photo, where the object meets the background, which must have a start-point, and an end point which returns to the start point..
Photoshop then calculates the location of items to keep as inside the closed brush line, and items to disappear as outside that brushed line
Tolerances can be individually set with an Eye-dropper between a blue shirt sleeve you want to keep, inside the brush mark, and the blue sea, blue car, or blue sky adjacent to that sleeve, outside the brush mark,..
you can add another combination of "Near Tolerances" by clicking "Add a Near Tolerance", then you select the green shoes inside the line, multi-select add, then click next, and click the green grass outside the region.. also additive multi-select
Photoshop then remembers the regions, the colors, patterns, and values, and all the other information you gave it (the only real important thing being what happens directly under the brush line you painted around your object, as it will automatically delete everything outside of that), click "Extract" and the object of your desire is removed perfectly
