Crate chromata 

Chromata

1000+ editor color themes as compile-time Rust constants.

Chromata provides every popular editor and terminal color theme as compile-time const data. No file parsing, no runtime allocation, one dependency (libm for no_std math). Add chromata to your Cargo.toml, write chromata::popular::gruvbox::DARK_HARD.bg, and get a hex color at zero cost.

Core Types

• Color — RGB color with hex conversion, WCAG luminance, contrast ratio, lerp
• Theme — 29 color fields + metadata (name, author, variant, contrast)
• ThemeBuilder — Fluent builder for constructing themes at runtime
• Variant — Dark or Light
• Contrast — High, Normal, or Low (WCAG-based)
• Base16Palette — The 16 base16 palette slots (used within Base24Palette)
• Base24Palette — Extended 24-slot palette (exported by base24 themes as PALETTE)

Quick Start

use chromata::popular::gruvbox;

let theme = gruvbox::DARK_HARD;
println!("Background: {}", theme.bg.to_css_hex());
println!("Is dark? {}", theme.is_dark());

Query APIs

use chromata::{find_by_name, filter_by_variant, Variant};

if let Some(theme) = find_by_name("Gruvbox Dark Hard") {
    println!("{}: {}", theme.name, theme.bg);
}
let dark_themes = filter_by_variant(Variant::Dark);
