Struct palette::Lch

#[repr(C)]
pub struct Lch<Wp = D65, T = f32> {
    pub l: T,
    pub chroma: T,
    pub hue: LabHue<T>,
    pub white_point: PhantomData<Wp>,
}

CIE L*C*h°, a polar version of CIE L*a*b*.

L*C*h° shares its range and perceptual uniformity with L*a*b*, but it’s a cylindrical color space, like HSL and HSV. This gives it the same ability to directly change the hue and colorfulness of a color, while preserving other visual aspects.

Fields

l: T

L* is the lightness of the color. 0.0 gives absolute black and 100.0 gives the brightest white.

chroma: T

C* is the colorfulness of the color. It’s similar to saturation. 0.0 gives gray scale colors, and numbers around 128-181 gives fully saturated colors. The upper limit of 128 should include the whole L*a*b* space and some more.

hue: LabHue<T>

The hue of the color, in degrees. Decides if it’s red, blue, purple, etc.

white_point: PhantomData<Wp>

The white point associated with the color’s illuminant and observer. D65 for 2 degree observer is used by default.

Implementations

impl<Wp, T> Lch<Wp, T>

pub fn new<H: Into<LabHue<T>>>(l: T, chroma: T, hue: H) -> Self

Create a CIE L*C*h° color.

pub const fn new_const(l: T, chroma: T, hue: LabHue<T>) -> Self

Create a CIE L*C*h° color. This is the same as Lch::new without the generic hue type. It’s temporary until const fn supports traits.

pub fn into_components(self) -> (T, T, LabHue<T>)

Convert to a (L\*, C\*, h°) tuple.

pub fn from_components<H: Into<LabHue<T>>>((l, chroma, hue): (T, T, H)) -> Self

Convert from a (L\*, C\*, h°) tuple.

impl<Wp, T> Lch<Wp, T>

where T: Zero + Real,

pub fn min_l() -> T

Return the l value minimum.

pub fn max_l() -> T

Return the l value maximum.

pub fn min_chroma() -> T

Return the chroma value minimum.

pub fn max_chroma() -> T

Return the chroma value maximum. This value does not cover the entire color space, but covers enough to be practical for downsampling to smaller color spaces like sRGB.

Return the chroma extended maximum value. This value covers the entire color space and is included for completeness, but the additional range should be unnecessary for most use cases.
