When I opened up my board to swap the switches, I realized it had unused RGB pads...soo of course I hand solder 60 2-3mm surface mount LEDs to it. Yep, last time I do that :-P But it worked, which was the fun part...
the sad part is, I don't even like RBG on computer gear
I'm not a huge RGB person, either. But my Thinkpad has plain white background LEDs. And even though I type blindly 98% of the time, I find it more comfortable to have some (slight) hinting when positioning.
Sad part for me: TIL that most keycaps with "shine through" need the LED above/north of the switch (else the LED mostly blinds the user), which means I need to rotate all switches by 180 deg. But the GMK caps (which are considered some of the "best") are known to cause trouble with that orientation. And some switches might be feel different as well.
Yeah - my vortex rebuild (1) has south facing LEDs, so they're basically useless. The only thing I really liked about shine thru's was the ability to occasionally change up the legend colors (ohh - maybe amber or yellow legends today? or blue!)
