Valid COLORTONE input
Choose a CSS named color from the built-in list. Name matching is case-insensitive after normalization.
Convert CSS Color Name (Colortone) used for readable CSS keywords and human-friendly swatch labels into formula-based CMYK percentages without an ICC profile, ready for basic print handoff and ink-percentage references.
Values are converted in the page with local TypeScript functions. No color value needs to be uploaded for this calculation.
Choose a color visually, use sliders, or paste a value.
