//! Material Design's 2014 colour palette: 19 palettes of ten shades, from
//! `c50` (the lightest) to `c900` (the darkest), sixteen of them with four
//! accents (`a100`, `a200`, `a400`, `a700`).
//!
//! The values are Material Design Lite's (`src/_color-definitions.scss`,
//! the `mdl-1.x` branch), Apache License 2.0, Copyright 2015 Google Inc.
//! Each shade is a `#rrggbb` string, for markup, styles and themes.
//!
//! ```
//! use rich_ext::palette::material::{BLUE_GREY, RED};
//!
//! assert_eq!(RED.c500, "#f44336");
//! assert_eq!(RED.a200, "#ff5252");
//! assert_eq!(BLUE_GREY.c900, "#263238");
