Implementations§

impl Color

pub fn color_space(&self) -> Option<ColorSpace>

Returns the ColorSpace of this colour, if it maps to a bounded RGB gamut.

Perceptual and CIE spaces (Lab, Lch, Oklab, Oklch, XyzD50, XyzD65) return None — they can represent colours outside any single RGB gamut.

pub fn in_gamut_of(&self, space: ColorSpace) -> bool

Returns true if this colour can be represented in space without clamping.

If the colour’s own space is a subset of space and the colour is in gamut of its own space, this returns true without conversion. Otherwise the colour is converted to the target space (via XyzD65) and the RGB channels are checked against [0,1].

impl Color

pub fn with_alpha(self, alpha: f32) -> Self

Returns a copy of this colour with a new alpha value (0.0–100.0).

For Named colours (which are always fully opaque), setting a non-100 alpha converts to Srgb. For Hex, the colour is round-tripped through Srgb to apply the new alpha.
