I wonder why people obsess so much with colorful keycaps and RGB lights. I suspect it's for aesthetic pleasure, not for enhanced ergonomics.

I got me a split keyboard so that I would never have to look at it. For me this is achieved by not moving the wrist, only moving the fingers. Then my hands do not slip and do not need vision-guided repositioning.

(My current keyboard is an Ergodox EZ, all black, no lights. It's fine enough, and thr ortholinear layout is very helpful, but the thumb cluster is clumsy, and the pinky columns are not staggered enough, so typing P or Q needs a wrist shift. I have 60g switches in the home row, so that fingers can rest on them without clicking, and 30g switches everywhere else. My plan is to build a Kyria which has a better geometry / ergonomics, so I made a Kyria-compatible layout to get used to it.)
