Struct CorePalette 

pub struct CorePalette {
    pub primary: TonalPalette,
    pub secondary: TonalPalette,
    pub tertiary: TonalPalette,
    pub neutral: TonalPalette,
    pub neutral_variant: TonalPalette,
    pub error: TonalPalette,
}

The six tonal ramps a Material scheme is drawn from.

Fields

primary: TonalPalette

The seed’s own hue at chroma max(48, seed chroma).

secondary: TonalPalette

The seed’s hue, muted (chroma 16).

tertiary: TonalPalette

The seed’s hue rotated +60°, chroma 24.

neutral: TonalPalette

The seed’s hue, near-gray (chroma 6) — surfaces and their content.

neutral_variant: TonalPalette

The seed’s hue, slightly more colored than Self::neutral (chroma 8) — outlines and surface-variant content.

error: TonalPalette

A fixed red ramp (hue 25, chroma 84), independent of the seed.

Implementations

impl CorePalette

pub fn of(seed: Color) -> Self

Derive all six ramps from one seed color (its alpha is ignored).

primary keeps the seed’s own chroma whenever that clears Material’s floor of 48, so a sufficiently colorful seed reappears verbatim as the light scheme’s primary (tone 40). A gray or black seed has no meaningful hue of its own: CAM16 reports ~209.5° for grays and whites and exactly 0° for pure black, and this module keeps that behavior rather than substituting a hue of its own — the chroma floor alone is what turns a colorless seed into a usable theme.
