Print-style CMYK color

Get a ready-to-paste cmyk() value for print-spec mockups, packaging and brochure layouts, or seeding fixture data for print and PDF workflows. CMYK is the subtractive ink model — cyan, magenta, yellow, and key (black) — each picked independently from 0–100%. The swatch is an approximate, naive RGB preview only and makes no color-profile or ICC accuracy claims; actual printed color depends on inks, paper, and profile.
