Enabling Rainbow Mode for Outlines

By default, Contour Shaders automatically matches border colors to the target—giving a green outline to a Creeper, a brown line to a Cow, and unique matching colors to other entities. If you want a more vibrant, animated aesthetic, you can switch to Rainbow Mode.

How to Enable Rainbow Mode

1. Press Escape in-game and navigate to Options > Video Settings.

2. Open your shader list and click into the settings menu for Contour Shaders.

3. Locate the Rainbow Mode toggle within the settings list.

4. Change the toggle from disabled to enabled.

5. Click Done or Apply to save the configuration and return to your game.

What Changes in Game

Once enabled, the standard entity-matched colors are replaced by cycling rainbow lines:

• Mobs and Players: Every creature and player around you will display brightly cycling rainbow borders rather than their creature-matched colors.
• Dropped Items: Any items resting on the ground will also display cycling rainbow outlines, making them easy to spot in dark caves or foliage.

Lighting, shadows, and water shaders remain unaffected, allowing you to enjoy vibrant outlines alongside standard realistic rendering.
