Short answer
The Pantone Matching System is a proprietary catalogue of numbered spot colours, each with printed swatches and a formula for mixing it from a small set of base inks. It gives designers and printers a shared reference so that a colour chosen from a swatch book can be mixed and printed consistently elsewhere. It is a system of standardised physical references rather than a colour space: its numbers are labels, not coordinates, and many of its colours lie outside what CMYK process printing or sRGB screens can reproduce.

Before shared ink references, a designer who wanted a particular colour had to send a sample and trust the printer to mix something close. Pantone, a printing firm that Lawrence Herbert joined in 1956 and took over in 1962, systematised its ink inventory into a set of base inks and a numbered catalogue of colours mixed from them, each shown as a printed swatch. A number could then travel instead of a sample: any printer with the base inks and the formula could mix the colour. That idea — a small set of base inks, published formulas, and a fan guide of swatches — is what made the system an industry reference for spot colour.
A Pantone colour is designed to be printed as its own premixed ink, a spot colour, not built from overlapping cyan, magenta, yellow and black dots. That is why it can reach colours process printing cannot: particularly clean oranges, vivid greens, deep blues, metallics and fluorescents. When a Pantone colour must be printed in CMYK or shown on screen, a conversion is used, and for many colours the result is a visible compromise. Swatch guides printed on coated and uncoated paper show the same ink looking different on each, which is a reminder that the number specifies an ink, and the result depends on the substrate.
Pantone numbers are identifiers. Adjacent numbers are not necessarily similar, there is no arithmetic between them, and there is no formula from a number to a colour; the definition is the physical standard and its measured data. That makes the system excellent for naming and matching specific colours and unsuitable for generating palettes, computing differences or describing colours outside the catalogue — jobs for CIELAB or OKLCH. It also means the system changes over time as colours are added, retired or reformulated, so the edition of a guide matters for critical matches.
Pantone has changed hands several times: it was bought by X-Rite in 2007, became part of Danaher when Danaher acquired X-Rite in 2012, and moved with X-Rite to Veralto when Danaher spun that company off in 2023. Its colour data is licensed; in 2022 Pantone colour values were removed from Adobe's standard libraries and made available through a separate subscription. Colourwise describes the system and names it nominatively but does not reproduce Pantone colour values or name lists, and any on-screen rendering of a Pantone colour elsewhere should be treated as an approximation.
Why: The spot colour lies outside the process gamut; the conversion is a compromise.
Fix: Print it as a spot ink, or approve the CMYK equivalent on a physical proof.
Why: Different paper (coated vs uncoated), ink film thickness or guide edition.
Fix: Specify the substrate, check against the matching guide and set a measured tolerance.
Why: Unlicensed or approximate RGB values, and a screen that cannot show the colour.
Fix: Judge against the physical guide under standard lighting.

FactModerate evidence
Lawrence Herbert, hired by Pantone's owners in 1956, bought the company's technological assets in 1962 and renamed it Pantone; its matching system consists of numbered colours shown as swatches in fan guides.
Caveat: Corporate history from a reference work; the exact launch year of the matching system was not independently verified and is given only as the early 1960s.

Pantone was acquired by X-Rite in 2007; Danaher acquired X-Rite in 2012; and Pantone became part of Veralto in the 2023 spin-off from Danaher.

Many colours in the Pantone Matching System lie outside the gamut of CMYK process printing and of sRGB.

Colourwise interpretationModerate evidence
Because Pantone numbers are identifiers rather than coordinates, the system is suited to specifying and matching particular colours but not to computing differences or generating palettes.
Based on: Follows from the system's structure as a numbered catalogue of physical references, compared with coordinate spaces such as CIELAB.
