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, 7.5YR, 10YR, and 2.5Y. Use this page to describe carbonate, silica, gypsum, and soluble salt precipitates and evaporites common to arid and semi-arid and semi-arid environments as well as very light-colored parent materials such as diatomaceous earth and volcanic ash. The book's light gray pages decrase sun glare. The color chips are recessed into each water-resistant page to allow dirt and debric to be wiped off easily with less effect on the color chips. 2009 Revised Edition. Chart Size: 6" x 8"
