Details
This pack allows you to fully customize the block outline color in Minecraft, giving your game a personalized visual style.
By default, it comes with the color #ffcc0080 ![]()
Customize Outline
There are two ways to set your own outline color:
1. Manual Method:
Edit the rendertype_lines.vsh file directly at:
assets/minecraft/shaders/core/rendertype_lines.vsh
Modify the line:
temp = vec4(1.0, 0.8, 0.0, 0.5); // RGBA
Replace with your desired RGBA values.
2. Web Generator:
Use the custom generator to create a pack in your desired color. Choose from sliders, HEX input, presets, or save your own.

â ď¸ Compatibility
Not compatible with shaderpacks (e.g. Iris, Optifine) as they override core shaders.
If you would like to use shaders with a custom outline. You will need to use shaders that have their own custom outline option such as:
Complementary Reimagined
Complementary Unbound
or Photon Shader
