Chromatic
Chromatic is a Fabric mod that drives Razer Chroma keyboards so the keyboard reflects the player's game state.
What it does
The keyboard lighting follows health, air, hunger and weather. Keys F1 to F4 show health, and the colour shifts to match the heart colour used in the game. Healing is shown as an animation, and the keyboard flashes red after a large amount of damage. Keys F5 to F8 show air, and keys F9 to F12 show hunger.
The number keys 1 to 9 display the quantity and durability of items in the hotbar and mark the selected slot. The lighting also reacts to the current weather. Chromatic needs Cloth Config API and Fabric API, and it requires the Razer Synapse software with the Chroma Connect module to reach the keyboard.
Chromatic runs on the client only, so a server does not need it and players join without installing it. The mod is open source under the GNU Lesser General Public License v2.1 only, and its configuration can be opened through Mod Menu. Public links exist for the source code and the issue tracker.
