Added in version 3.2.0, I may decide to iterate further on it. Let me know what you think.

I was trying to find a way to have one team in a minigame see their other teammates glowing effect, but not the enemy team. My idea to solve this was to have each team see their teammates glow color, and have the other ones a 'transparent' color, but the color limitation is RGB instead of ARGB.

TLDR; I want to be able to have the glowing effect be invisible/not render for specific targets

Is it possible to add something to this effect?

Similar request on the Minecraft Feedback website, that makes a lot more sense than how I tried explaining it

Uhm, if you are a developer you can look into my other mod LightWithin dev branch, where i've added something like this. Otherwise i may add something like that to ColoredGlowLib too at some poinylt

Unfortunately not a developer, but it would be nice to have as part of CGL as well if you ever get around to it
