CMYK to Pantone Converter

About This Tool

This tool maps CMYK color values to the nearest Pantone swatch. It accepts C, M, Y, and K as percentage inputs, converts them to a perceptual color space (CIELAB), and searches a Pantone swatch library to identify the closest match using Delta E2000. The output includes the Pantone code, Pantone name, and hex/RGB values for easy integration into design and production workflows. This approach supports designers and printers by providing a practical, repeatable method to align CMYK artwork with Pantone branding where spot colors are required. The system is designed to work with standard print conditions and acknowledges that exact matches are constrained by the differences between CMYK and Pantone ink sets. Core benefits include faster color decision-making, improved color consistency across campaigns, and a straightforward way to document color choices for proofs and production specs. Use cases include packaging design, brand guides, and print procurement where Pantone compatibility is a requirement. Unique value lies in offering an automated, measurement-based estimation rather than manual eyeballing, with explicit delta E metrics to support decision-making across multiple vendors. Core features comprise four numeric inputs, a nearest Pantone result with delta E distance, and outputs suitable for downstream workflows (hex/RGB). The tool supports single-color conversions and can be integrated into color-management pipelines for prepress and production teams.
