Struct Color 

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

An sRGB color with 8-bit channels.

Fields

r: u8

g: u8

b: u8

Implementations

impl Color

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

Create a new color from RGB components.

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

Create a color from a 24-bit hex value (e.g., 0xFF8800).

pub const fn to_hex(self) -> u32

Serialize the color as a 24-bit hex value (e.g., 0xFF8800).

pub fn to_css_hex(self) -> String

Format the color as a CSS hex string (e.g., "#ff8800").

pub const fn to_f32(self) -> (f32, f32, f32)

Convert to floating-point RGB in [0.0, 1.0].

pub fn luminance(self) -> f64

Relative luminance per WCAG 2.0.

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

WCAG contrast ratio between two colors.

pub fn lerp(self, other: Color, t: f32) -> Color

Linear interpolation between two colors.

t is clamped to [0.0, 1.0]. Interpolation is performed in sRGB space, matching the behavior of matplotlib, ParaView, and most scientific visualization tools.

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 Hash for Color

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
