Struct Palette 

pub struct Palette {
    pub heading: &'static str,
    pub option: &'static str,
    pub metavar: &'static str,
    pub command: &'static str,
}

Semantic colours for a help page, named in the same vocabulary as {$…} tags.

Each field is a style specification ("cyan+bold", "heading", "bright-cyan"). Role names expand once: mapping metavar to "heading" uses the built-in heading colour, not a remapped heading. The renderer still writes SGR directly.

Fields

heading: &'static str

Headings such as Usage: and Options:. Default "heading" (yellow + bold).

option: &'static str

Flag and option literals. Default "option" (green + bold).

metavar: &'static str

Metavariables such as <FILE>. Default "metavar" (magenta + bold).

command: &'static str

Subcommand names. Default "command" (green + bold).
