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

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

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::{OwoColorize, 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", so this trait is not object safe.
