Kairo's Color Filters

The filters are set from an in-game menu that opens through Mod Menu, with a key bound under Options and Controls for the same screen. Presets set all sliders at once, and each slider can then be fine-tuned, shows its value in a tooltip and resets on its own. A separate key flips the whole effect off instantly, which makes comparing against vanilla simple in the middle of a game.

The mod offers two modes: World Only keeps the HUD in its normal look, while Whole Screen applies the filter to everything, closest to the NVIDIA original. The filter runs on the graphics card in one pass, and the author describes its performance cost as zero. Settings are kept between sessions. The mod is client-side only, so servers need nothing, and it is released under the MIT License without being open source. Only Fabric files are published, for 1.20 – 26.3 across 13 release versions, and the latest is 1.3.3+26.3 for 26.3.

The author notes that the filters work alongside shader packs and resource packs, and that resource packs are built to pair with shader packs where possible. Shader packs are external software, so a shader pack is required for the features that depend on one.
