# Licence inventory Colour Tools is `GPL-3.0-or-later`; the full project licence is at `../LICENSE`. `THIRD_PARTY_NOTICES.md` identifies shipped runtime packages. Release preparation collates the exact installed licence files for every locked runtime package into `npm-runtime-licenses.txt`. `colorjs.io-MIT.txt` is retained separately because Color.js supplies the core standards-aligned colour conversion primitives used by the application.
