The Pantone Matching System (PMS) is a standardised colour reproduction system. Pantone began as a commercial printing company in the 1950s, and the systemisation of their pigments and inks was instigated by newly employed part-timer, Lawrence Herbert, in 1956. The system, whereby each colour is designated a number, allows designers to colour match pretty accurately, regardless of the equipment used to produce the colour. I came across the Pantone Guides early in my design career, and could label the world around me by Pantone number. I subsequently lost much of that familiarity because my work took my in the direction of the CMYK world, but some numbers remain entrenched.
