I've been using keyboards with RGB backlight for the past 7 or so years and I grew convinced that it's kinda useless — you mostly pick one scheme and stick to it.
And yet, when it's not there, it feels like something important is missing.

The most useful thing I could come up with was switching to red backlight before locking the screen and to green after it gets unlocked. And blue was used as an indicator that it's safe to undock the laptop.
No, it does have its uses 😂
