Applies a pipeline of adjustments to every colour, one operation per line: lighten / darken N%, saturate / desaturate N%, grayscale, rotate N (degrees), complement, invert, alpha 0–1, mix <colour> N%, tint N% (toward white), shade N% (toward black). Lightness and chroma operate in perceptual OKLCH with gamut fitting, or in HSL when you need the classic behaviour of Sass and Less. The table shows every intermediate step; the preview shows before → after swatches. Everything runs locally.
