Lighting

Set a solid RGB color on a wired Logitech G-series keyboard, backed by the HID++ 0x8080 perKeyLighting feature. OpenLogi drives it as one static color rather than per-key effects.

From the GUI

Select the keyboard in the device carousel; its detail panel has a lighting section with:

Color swatches — a small palette of preset accent colors.
On / off — toggle whether the static color is applied.
Brightness — a 0–100 slider. The level is pushed to the keyboard when you release the slider, so dragging doesn’t stream a burst of updates.

Your choice is saved per device under [devices.<key>.lighting] in the config (enabled, color, brightness).

Lighting targets wired (USB) keyboards — wireless mice and Bolt / Unifying receivers are skipped. As always, quit Logi Options+ first so OpenLogi can own the device.

Status: macOS + Linux, wired G-series keyboards. See 0x8080 perKeyLighting for the protocol detail.
