Pantone Color Converter

Enter a color, get the closest approximate Pantone-name match.

A free online Pantone converter — type a hex or RGB value and get the nearest named Pantone spot color, ranked by similarity. This is an unofficial approximation using publicly available, commonly-published RGB values — not official, licensed Pantone Matching System (PMS) data. No signup, runs entirely in your browser.

Hex or RGB

These are approximate nearest matches from publicly available RGB references, not official or licensed Pantone Matching System values. For print production, always confirm the exact PMS number against a physical Pantone swatch book.

What does a Pantone converter do?

A Pantone converter takes a hex or RGB value and matches it to the closest of a set of named Pantone spot colors — since hex and RGB are screen color spaces and Pantone's Matching System (PMS) is a proprietary, licensed ink-mixing standard, any hex-to-Pantone match is inherently an approximation. This tool ranks a set of commonly-published, publicly available approximate Pantone RGB values by visual distance and returns the nearest ones, so you get a rough named reference point for any color instead of just a code. It does not reproduce, and does not claim to reproduce, official Pantone color data.

Why this isn't official Pantone matching

Pantone, a business of X-Rite, owns and licenses the Pantone Matching System (PMS) — a proprietary catalog of physical ink formulations and their exact digital equivalents. Accessing the official values requires a paid license and Pantone's own software or physical swatch books. This tool has no access to that licensed data. Instead it uses a small set of widely-published, commonly-cited approximate RGB conversions for well-known named Pantone spot colors, compiled from public sources. The result is a useful starting point for identifying "which Pantone is this roughly," not a certified or production-accurate color match.

How "closest" is measured

The tool uses the "redmean" color distance formula — a weighted variant of Euclidean distance in RGB space that adjusts each channel's weight based on the overall redness of the two colors being compared. It's a well-established, low-cost approximation of human color perception, noticeably more accurate than plain unweighted RGB distance while still being fast to compute. The same formula and approach power our Color Name Finder tool.

Common uses

Getting a rough sense of which Pantone family a brand or design color falls into before confirming against an official swatch book, describing a color to a print vendor in familiar Pantone-style language, or satisfying curiosity about what a picked-up hex value roughly corresponds to in spot-color terms. For anything going to print or requiring exact color reproduction, always verify against a physical Pantone guide or your printer's licensed color library.

Frequently asked questions

No — this tool is not affiliated with or licensed by Pantone/X-Rite, and it does not have access to the official, proprietary Pantone Matching System (PMS) color values. It compares your hex or RGB input against a small set of commonly-published, publicly available approximate RGB conversions for well-known Pantone spot colors and returns the closest match. Treat the result as a rough visual approximation, not an exact or certified color match.

Enter a hex code (like #C8102E) or an RGB value, or pick a color with the swatch picker. The tool compares it against a list of commonly-referenced named Pantone spot colors and shows the closest approximate match, plus the next 2 closest, ranked by visual distance.

They're widely-published, commonly-cited approximate RGB conversions for well-known named Pantone spot colors — not scraped or extracted from Pantone's licensed digital color libraries. Pantone/X-Rite own and license the exact proprietary color standard, and printed or on-screen approximations can vary between sources, monitors, and substrates.

Using the "redmean" color distance formula — a weighted variant of Euclidean distance in RGB space that accounts for how human vision is more sensitive to some color channels than others, giving noticeably better matches than plain RGB distance.
