Struct Color 

pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
}

A color in RGB format.

Fields

r: u8

Red component (0-255).

g: u8

Green component (0-255).

b: u8

Blue component (0-255).

Implementations

impl Color

pub const fn new(r: u8, g: u8, b: u8) -> Self

Create a new color from RGB values.

pub const fn from_hex(hex: u32) -> Self

Create a color from a hex value (0xRRGGBB).

pub fn to_hex(&self) -> String

Convert to hex string (e.g., “#009688”).

pub const fn to_rgb(&self) -> (u8, u8, u8)

Convert to RGB tuple.

pub fn to_ansi_fg(&self) -> String

Convert to ANSI 24-bit foreground escape code.

pub fn to_ansi_bg(&self) -> String

Convert to ANSI 24-bit background escape code.

pub fn luminance(&self) -> f64

Calculate relative luminance for contrast calculations.

Uses the WCAG formula for relative luminance.

pub fn contrast_ratio(&self, other: &Color) -> f64

Calculate WCAG contrast ratio between this color and another.

Returns a value between 1.0 (no contrast) and 21.0 (max contrast). WCAG AA requires 4.5:1 for normal text, 3:1 for large text.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Color

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Color

fn eq(&self, other: &Color) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
