## Colour palettes

Ten of the palettes offered in Settings › Appearance are the work of their own
projects and are used under the MIT licence. Only the published colour values
are used — no code, and nothing from anyone else's reimplementation of them.
The values as fetched from each project are recorded in
`.palette-sources/palettes-upstream.md`, and the shades between them are
derived by `scripts/build-palettes.py`, which also lifts any tier that would
not meet the contrast ihasmail claims.
