Example

use owo_colors::OwoColorize;

println!("My number is {:#x}!", 10.green());
println!("My number is not {}!", 4.on_red());

How to decide which method to use

Do you have a specific color you want to use?

Use the specific color’s method, such as blue or on_green.

Do you want your colors configurable via generics?

Use fg and bg to make it compile-time configurable.

Do you need to pick a color at runtime?

Use the color, on_color, truecolor or on_truecolor.

Do you need some other text modifier?

• bold
• dimmed
• italic
• underline
• blink
• blink_fast
• reversed
• hidden
• strikethrough

Do you want it to only display colors if it’s a terminal?

1. Enable the supports-colors feature
2. Colorize inside if_supports_color

Do you need to store a set of colors/effects to apply to multiple things?

Use style to apply a Style.

fn strikethrough(&self) -> StrikeThroughDisplay<'_, Self>

fn color<Color: DynColor>( &self, color: Color, ) -> FgDynColorDisplay<'_, Color, Self>

Set the foreground color at runtime. Only use if you do not know which color will be used at compile-time. If the color is constant, use either OwoColorize::fg or a color-specific method, such as OwoColorize::green,

use owo_colors::{OwoColorize, AnsiColors};

println!("{}", "green".color(AnsiColors::Green));

fn on_color<Color: DynColor>( &self, color: Color, ) -> BgDynColorDisplay<'_, Color, Self>

Set the background color at runtime. Only use if you do not know what color to use at compile-time. If the color is constant, use either OwoColorize::bg or a color-specific method, such as OwoColorize::on_yellow,

use owo_colors::{OwoColorize, AnsiColors};

println!("{}", "yellow background".on_color(AnsiColors::BrightYellow));

fn fg_rgb<const R: u8, const G: u8, const B: u8>( &self, ) -> FgColorDisplay<'_, CustomColor<R, G, B>, Self>

fn bg_rgb<const R: u8, const G: u8, const B: u8>( &self, ) -> BgColorDisplay<'_, CustomColor<R, G, B>, Self>

Set the background color to a specific RGB value.

fn truecolor(&self, r: u8, g: u8, b: u8) -> FgDynColorDisplay<'_, Rgb, Self>

Sets the foreground color to an RGB value.

fn on_truecolor(&self, r: u8, g: u8, b: u8) -> BgDynColorDisplay<'_, Rgb, Self>

Sets the background color to an RGB value.

fn style(&self, style: Style) -> Styled<&Self>

Apply a runtime-determined style

fn if_supports_color<'a, Out, ApplyFn>( &'a self, stream: impl Into<Stream>, apply: ApplyFn, ) -> SupportsColorsDisplay<'a, Self, Out, ApplyFn>

where ApplyFn: Fn(&'a Self) -> Out,

Apply a given transformation function to all formatters if the given stream supports at least basic ANSI colors, allowing you to conditionally apply given styles/colors.

Requires the supports-colors feature.

use owo_colors::{Stream, OwoColorize};

println!(
    "{}",
    "woah! error! if this terminal supports colors, it's blue"
        .if_supports_color(Stream::Stdout, |text| text.bright_blue())
);

This function also accepts supports_color version 2’s Stream, and also the deprecated supports_color version 1’s Stream.

use owo_colors::OwoColorize;
#[cfg(feature = "supports-colors")]
use supports_color::Stream;

println!(
   "{}",
   "woah! error! if this terminal supports colors, it's blue"
      .if_supports_color(Stream::Stdout, |text| text.bright_blue())
);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
