The Munsell Color System describes a soil's color, based on Hue, Value & Chroma. The Munsell Book is a collection of color chips with varying degrees of hue, value & chroma. Take a small soil sample and match it up with the appropriate color chip to determine that soil's Munsell "code.".
Munsell Color Notations Below is a list of Munsell color notations found in the various color books and charts. Looking for a specific color notation? Use this link to send us an inquiry. This document contains Munsell soil color codes and their corresponding descriptions.
There are over 200 entries listing the Munsell gradient number, Munsell soil color code, and brief description for each soil color. The codes range from 10R to 10Y and represent variations in hue, value, and chroma for different shades of red, yellow, and brown soils. The Munsell Soil Color Chart is particularly valuable in tracking environmental shifts.
Subtle variations in soil color can indicate changes in moisture levels, organic content, or chemical composition. With a soil color book with Munsell notations, a science student or teacher can visually connect soil colors with natural environments of the area, and students can learn to read and record the color, scientifically. Soil color by Munsell notation is one of many standard methods used to describe soils for soil survey.
Munsell soil color charts were developed with the U.S. soil conservation service for classifying soil color, but may also be used for rocks, archaeological specimens, and other natural products. Munsell charts are a standard tool for geologists, civil engineers, and soil scientists.
The tabbed charts include 10R, 7.5R, 5R, 2.5YR, 5YR, 7.5YR, 10YR, 2.5Y, 5Y and 10Y. Albert Munsell, a professor and artist, devised a method of evaluating and classifying colors based on three properties; hue, value, and chroma, also referred to as (HVC). These properties have helped soil scientists standardize and record their observations through the Munsell Soil Color Chart, described in detail below.
Table of. This revised edition features the same colors available in previous books plus additional color charts. Included are a 10Y and 5GY soil chart for glauconite soils, a 5R soil chart for Australia and Southeast Asia, and a 7.5R soil chart for tropical and semi-tropical soils.
A Munsell high value, low chroma "white" page shows half steps from 8.5 to 9.5 in value with chromas of 1 and 2 for N. Understand the Munsell Color System with our visual guide on understanding hue, value, and chroma for accurate soil color identification.

The Munsell Soil Color Charts are an affordable way to evaluate the type of soil that is present within a given area. The book is set up to allow users to make soil color evaluations in the field quickly and easily.
