Trait nannou::color::Shade

pub trait Shade: Sized {
    type Scalar: Float;

    // Required method
    fn lighten(&self, amount: Self::Scalar) -> Self;

    // Provided method
    fn darken(&self, amount: Self::Scalar) -> Self { ... }
}

The Shade trait allows a color to be lightened or darkened.

use palette::{LinSrgb, Shade};

let a = LinSrgb::new(0.4, 0.4, 0.4);
let b = LinSrgb::new(0.6, 0.6, 0.6);

assert_eq!(a.lighten(0.1), b.darken(0.1));

Required Associated Types

type Scalar: Float

The type of the lighten/darken amount.

Required Methods

fn lighten(&self, amount: Self::Scalar) -> Self

Lighten the color by amount.

Provided Methods

fn darken(&self, amount: Self::Scalar) -> Self

Darken the color by amount.

Object Safety

This trait is not object safe.
