Module palette 

Named colours: a palette file ({"name": "#RRGGBB", ...}) that all drawing code refers to by name. The game says which names it needs; a theme is another palette file with exactly the names of the default one (theme_problems). As a format (ADR-0007): PaletteRon.

Structs

PaletteDef

The validated palette: colour name → RGB.

PaletteRon

A palette file (palette, .ron), checked as PaletteDef::from_source says against the colours the game requires.

Functions

format_hex

Formats RGB as lowercase #rrggbb.

line_of_key

1-based line of the first line containing "key", for error positions.

parse_hex

Parses #RRGGBB (hex digits in either case) into RGB.

theme_problems

What is wrong with theme palette (its file shown as file): it must define exactly the colour names of the default theme’s base (a name missing would leave something unpainted; an extra one is a typo).
