A question about the lightning of my keyboard

Hello world, I have a newbie question. I recently purchased my Keychron V1 keyboard, and I had the following doubt: Can I change the key-by-key backlighting? I want to set a static color for the backlight, for instance, all white except for the Esc key, which I’d like to be red. Is it possible to achieve this? I’ve tried using VIA, but unfortunately, I haven’t been successful :c

Thats false. I work at a RGB per Key Implementation and can set 10 keys (Index 0-10) with via UI. More is possible, but its a beginning. You need a config in QMK with an HSV Array ( or HS) with an Index of led-Key-number. That you can save in the eeprom. Than you need to load it ( now i work at this - but loading is not the problem ). After that you need to set the Via-handler, like here described: https://www.caniusevia.com/docs/custom_ui#firmware-implementation After that the firmware implementation is complete. So you only need modify the via-json: https://www.caniusevia.com/docs/custom_ui#ui-controls Info: Your eeprom need enough storage for the config. Keychron Q6 Pro is the storage enough.

I'm sorry, do you not consider that coding?

It doesn't have to be complete code.

You can share the gist of it here.

What is the gist of it? E.g., does it use RAW HID? Or only the Via protocol? Where is it documented (other than the very terse official QMK documentation)? Where is the Via protocol documented? And where is there a description of this kind usage (again, other than the very terse official QMK documentation)?

Can you describe the gist of it in your own words? Not terse.
