Enum Mixing 

#[non_exhaustive]
pub enum Mixing {
    Normal,
    Perceptual,
    Oklab,
    Linear,
}

How colours mix between stops (GradationData mixing word).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Normal

通常: straight sRGB values.

Perceptual

知覚的: a pigment-like mix where the darker colour weighs more (black to white is about a fifth of the way at mid with no luminance correction, a third with 3). Approximated as Oklab with that weighting: grey ramps within a few levels, colour pairs off by up to a few tens, because CSP also darkens some pairs in between.

Oklab

知覚的 (Photoshop互換): Oklab.

Linear

リニア (Photoshop互換): linear light.
