SplatColour is a tool for editing ink colour configurations in Splatoon. It allows easy editing of the GfxSetting param files for adding custom ink colour sets.

To use it, there are some specific requirements:

  • You must have a modded Wii U with the nohash clients
  • You must have a PC with a Cafiine server running and serving a modified Static.pack with your changes
  • This can only be used when you are the host of a lobby: in public matches, the host is always at the top of the player list. Usually sticking in a lobby for a few games will get you the host spot

You can download the tool and its source code from GitHub.
