Work with #270045

Inspect equivalent formats, text contrast, palette steps, hue relationships, and copy-ready CSS for any opaque color entered as HEX, RGB, HSL, HWB, OKLCH, or a CSS keyword.

Tune OKLCH, then keep its sRGB fallback honest.

Adjust perceptual lightness, chroma, and hue. The instrument keeps the authored OKLCH value separate from the six-digit fallback used by the rest of this workspace.
