To be fair, even though PMS or the Pantone Matching System is the most popular they aren’t the only game out there.
So here is another that can be used. The Munsell color system.
The fundamentals of color are based on Albert H. Munsell’s theory of color.
The way you visually match color today is the result of Albert H. Munsell’s work nearly a century ago. In fact, modern day color theory and mathematical color system is based on Munsell’s theory of color.
An artist and an educator, Munsell developed his color theory to bring clarity to color communication by establishing an orderly system for accurately identifying every color that exists. Munsell based his system on what he defined as “perceived equidistance” — the human visual system’s perception of color.
Your Color is Munsell's Business
Munsell helps you communicate and reproduce color consistently with color standards developed using Munsell color theory. Choose a standard color from the Munsell books of color and color sheets or have them develop a custom color management solution for you — giving you freedom to design your own unique color instead of being forced to choose a predetermined color from a fandeck.
How Munsell Color Notation Works
Here’s How Munsell Color Theory Works…
Munsell color order system is based on a three-dimensional model depicted in the Munsell color tree. Each color has three qualities or attributes:
Hue – color such as red, orange, yellow, etc.
Value – the lightness or darkness of a color
Chroma – the saturation or brilliance of a color
Hue, value and chroma are also referred to as (HVC)
Munsell Color Theory is based on a three-dimensional model in which each color is comprised of three attributes of hue (color itself), value (lightness/darkness) and chroma (color saturation or brilliance)
The Munsell Color system is set up as a numerical scale with visually uniform steps for each of the three color attributes — in Munsell color notation, each color has a logical and visual relationship to all other colors.
Value indicates the lightness of a color. The scale of value ranges from 0 for pure black to 10 for pure white. Black, white and the grays (as shown in figure 2) between them are called “neutral colors”. They have no hue. Colors that have a hue are called “chromatic colors.” The value scale applies to chromatic as well as neutral colors. The value scale is illustrated for all neutral colors on the chart labeled Munsell’s Nearly Neutral, included in this book of color.
This is a very basic introduction to the Munsell Color System.
