Expand description

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

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

Variants

Black

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

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

DarkGray

Color #0 (foreground code 90, background code 100).

Red

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

LightRed

Color #1 (foreground code 91, background code 101).

Green

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

LightGreen

Color #2 (foreground code 92, background code 102).

Yellow

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

LightYellow

Color #3 (foreground code 93, background code 103).

Blue

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

LightBlue

Color #4 (foreground code 94, background code 104).

Purple

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

LightPurple

Color #5 (foreground code 95, background code 105).

Magenta

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

LightMagenta

Color #5 (foreground code 95, background code 105).

Cyan

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

LightCyan

Color #6 (foreground code 96, background code 106).

White

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

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

LightGray

Color #7 (foreground code 97, background code 107).

Fixed(u8)

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

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

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

Rgb(u8u8u8)

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

Implementations

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

See also Style::prefix.

Examples
use nu_ansi_term::Color::Green;

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

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

See also Style::infix.

Examples
use nu_ansi_term::Color::{Red, Yellow};

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

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

See also Style::suffix.

Examples
use nu_ansi_term::Color::Purple;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

Examples
use nu_ansi_term::Color;

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

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

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

You can turn a Color into a Style with the foreground color set with the From trait.

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