Expand description

A colour is one specific type of ANSI escape code, and can refer to either the foreground or background colour.

These use the standard numeric sequences. See http://invisible-island.net/xterm/ctlseqs/ctlseqs.html

Variants

Black

Colour #0 (foreground code 30, background code 40).

This is not necessarily the background colour, and using it as one may render the text hard to read on terminals with dark backgrounds.

Red

Colour #1 (foreground code 31, background code 41).

Green

Colour #2 (foreground code 32, background code 42).

Yellow

Colour #3 (foreground code 33, background code 43).

Blue

Colour #4 (foreground code 34, background code 44).

Purple

Colour #5 (foreground code 35, background code 45).

Cyan

Colour #6 (foreground code 36, background code 46).

White

Colour #7 (foreground code 37, background code 47).

As above, this is not necessarily the foreground colour, and may be hard to read on terminals with light backgrounds.

Fixed(u8)

A colour number from 0 to 255, for use in 256-colour terminal environments.

  • Colours 0 to 7 are the Black to White variants respectively. These colours can usually be changed in the terminal emulator.
  • Colours 8 to 15 are brighter versions of the eight colours above. These can also usually be changed in the terminal emulator, or it could be configured to use the original colours and show the text in bold instead. It varies depending on the program.
  • Colours 16 to 231 contain several palettes of bright colours, arranged in six squares measuring six by six each.
  • Colours 232 to 255 are shades of grey from black to white.

It might make more sense to look at a colour chart.

RGB(u8u8u8)

A 24-bit RGB color, as specified by ISO-8613-3.

Implementations

The prefix bytes for this colour as a Style. These are the bytes that tell the terminal to use a different colour or font style.

See also Style::prefix.

Examples
use ansi_term::Colour::Green;

assert_eq!("\x1b[0m",
           Green.suffix().to_string());

The infix bytes between this colour and next colour. These are the bytes that tell the terminal to use the next colour, or to do nothing if the two colours are equal.

See also Style::infix.

Examples
use ansi_term::Colour::{Red, Yellow};

assert_eq!("\x1b[33m",
           Red.infix(Yellow).to_string());

The suffix for this colour as a Style. These are the bytes that tell the terminal to reset back to its normal colour and font style.

See also Style::suffix.

Examples
use ansi_term::Colour::Purple;

assert_eq!("\x1b[0m",
           Purple.suffix().to_string());

Returns a Style with the foreground colour set to this colour.

Examples
use ansi_term::Colour;

let style = Colour::Red.normal();
println!("{}", style.paint("hi"));

Returns a Style with the foreground colour set to this colour and the bold property set.

Examples
use ansi_term::Colour;

let style = Colour::Green.bold();
println!("{}", style.paint("hey"));

Returns a Style with the foreground colour set to this colour and the dimmed property set.

Examples
use ansi_term::Colour;

let style = Colour::Yellow.dimmed();
println!("{}", style.paint("sup"));

Returns a Style with the foreground colour set to this colour and the italic property set.

Examples
use ansi_term::Colour;

let style = Colour::Blue.italic();
println!("{}", style.paint("greetings"));

Returns a Style with the foreground colour set to this colour and the underline property set.

Examples
use ansi_term::Colour;

let style = Colour::Purple.underline();
println!("{}", style.paint("salutations"));

Returns a Style with the foreground colour set to this colour and the blink property set.

Examples
use ansi_term::Colour;

let style = Colour::Cyan.blink();
println!("{}", style.paint("wazzup"));

Returns a Style with the foreground colour set to this colour and the reverse property set.

Examples
use ansi_term::Colour;

let style = Colour::Black.reverse();
println!("{}", style.paint("aloha"));

Returns a Style with the foreground colour set to this colour and the hidden property set.

Examples
use ansi_term::Colour;

let style = Colour::White.hidden();
println!("{}", style.paint("ahoy"));

Returns a Style with the foreground colour set to this colour and the strikethrough property set.

Examples
use ansi_term::Colour;

let style = Colour::Fixed(244).strikethrough();
println!("{}", style.paint("yo"));

Returns a Style with the foreground colour set to this colour and the background colour property set to the given colour.

Examples
use ansi_term::Colour;

let style = Colour::RGB(31, 31, 31).on(Colour::White);
println!("{}", style.paint("eyyyy"));

Paints the given text with this colour, returning an ANSI string. This is a short-cut so you don’t have to use Blue.normal() just to get blue text.

use ansi_term::Colour::Blue;
println!("{}", Blue.paint("da ba dee"));

You can turn a Colour into a Style with the foreground colour set with the From trait.

use ansi_term::{Style, Colour};
let green_foreground = Style::default().fg(Colour::Green);
assert_eq!(green_foreground, Colour::Green.normal());
assert_eq!(green_foreground, Colour::Green.into());
assert_eq!(green_foreground, Style::from(Colour::Green));
