Rainbow Glow
by DrFloofers
Rainbow Glow lets an admin or player make a character glow with a rainbow effect through a single command on Fabric for Minecraft 1.21.4.
What it does
A glow command gives the chosen character a rainbow, portal-like glowing effect. The effect is applied to a character entity, so the glow follows that character as it moves. The mod is aimed at roleplay sessions, admin-run events and creative screenshots, where a character should stand out from the rest of the scene.
Rainbow Glow is a lightweight Fabric mod and needs Fabric API to load. Installation covers the server and each player's game. Files are published only for Fabric and only for 1.21.4, in alpha form, under the MIT License, and the mod is not open source.
Key features
Glow command
A command switches the rainbow glow on for a character, giving a portal-like look without extra setup.
Character glow effect
The glow is applied to a character entity, so it stays attached to the character while it moves around.

Use cases
Roleplay and events
Game masters can mark a character during roleplay sessions or admin-run events so players can follow the focus of a scene.
Creative screenshots
Creators who take screenshots can make a character glow for a striking image without building special lighting.
Who it’s for: Server owners, admins and streamers who want a character to glow in a rainbow effect on a Fabric 1.21.4 setup. Players who run roleplay or creative events may also use it, provided the server runs it too.
How it compares
Rainbow Glow runs on Fabric and is client and server, with files for 1.21.4 only. GowingBlockOutlines is also a Fabric mod, but it targets 1.21 – 1.21.11 and is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, not the MIT License. Rainbow Ore is a Fabric mod for 1.21.8 only, client and server, under All rights reserved, so it covers a different range of game versions and a different license.
