Extension trait for colorizing a type which implements any std formatter (Display, Debug, UpperHex, etc.)

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 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));

Set the background color to a specific RGB value.

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