Customizable Blockoutlines
Customizable Blockoutlines lets players change the color and rainbow speed of block outlines through an in-game config menu.
What it does
The mod adds a way to customize the outline drawn around the block a player is looking at, using an in-game configuration screen rather than editing files. The screen offers a color wheel for picking the outline color. Only the client needs it, so players can use it on a server without the server installing anything. It requires KotlinForForge, and is published for NeoForge only, for 1.21.1.
Key features
In-game outline color
A color wheel in the config menu sets the color of block outlines without restarting the game.

The outline can cycle through rainbow colors, with the change speed adjustable in the same menu.
Single-purpose config screen
The mod does one thing, changing how block outlines look, and exposes only the options for that.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
