Rainbow Health Bar - Custom Hearts

Players who want their health display to look different can use the mod to recolor hearts. It offers a rainbow health bar mode that cycles through colors, a custom color mode, and an unchanged mode that keeps the default look. A health indicator text can be shown alongside the bar, and the mod includes textures for absorption, poison, wither and frozen hearts. An armor bar can have its height adjusted.

The mod is built on Simple Health Bar, which the author adapted for Fabric after finding no other mod that drew hearts above the hotbar in a different color. The author had permission from the creator of the original mod to modify its code and add the rainbow hearts. Rainbow coloration does not cover hearts correctly when a texture pack changes their shape, so the mod keeps the default heart texture for that case.

The mod is released under All rights reserved and is not open source. It runs on Fabric only, for game versions 1.21.1 – 26.2, with the latest file 1.1.3+1.21.1 for 1.21.1, published on 2026-06-22. Only the client needs it, so players can join a server without installing it.
