GEMINI LIGHT RECOLOURS
Zip folder includes:
Black, White, Ergo, Red, Yellow, Green, Cyan, Blue, Magenta.
Light will still change colour when near a butterfly though obviously if the butterfly is the same colour as the mod one it could be a little confusing.
Black may seem silly but the light still changes when necesarry so if you want Gemini to be "off" unless near a butterfly, black will do that.
Put the colour you want into your mods folder.
Base = Light inside the lamp
Light = Light given off by the lamp
2 people now have said they get a fatal error when launching with the light colour. When I manage to figure out what causes the error and will attempt to fix.
If it doesn't work, try verifying game files.
