About this Mod

The RGB Outline Block Selection is a simple and lightweight client-side Minecraft mod that replaces the default block selection outline with smooth animated RGB edges. This mod is designed to maintain a vanilla feel while providing a more modern and colorful block highlight. It only changes the visual outline effect and does not add unnecessary systems, heavy rendering features, or additional gameplay mechanics, so the performance impact remains minimal and suitable for everyday gameplay. Additionally, this mod does not require you to install the Fabric API mods, this mod is STANDALONE.
