Universal Color Converter

Convert between RGB, Hex, CMYK, and Pantone (approx.). Live, bidirectional, single source of truth.
Copy Hex Copy RGB Copy CMYK Copy Pantone
Accepts #RGB, #RRGGBB. Case-insensitive.
Values 0-255.
Converted using standard formula. Real print output may vary by profile/stock.
Uses a small built-in library for demo purposes and nearest-match search in sRGB. For production, replace with your Pantone license/color bridge data.
Notes: RGB,<->Hex is exact. RGB<->CMYK is a mathematical approximation and depends on print profiles. Pantone matches here are approximate and limited to the included library.
Computed Values
Built for education: RGB/Hex/CMYK conversions are generic; Pantone mapping uses a curated subset and Euclidean sRGB distance.
