This item contains the 7 standard cards plus the additional 7.5R and 5R, as described below.

From the preface we get; Soil colors are most conveniently measured by comparison with a color chart. The collection of charts generally used with soils is a modified version of the collection appearing in the Pocket Edition of the Munsell Book of Color and includes only that portion needed for soils, about one-fifth of the entire range found in the complete edition of the Book of Color. The seven charts in the Soil Collection display 196 different standard color chips systematically arranged according to their Munsell notations, on cards carried in a loose leaf notebook. The arrangement is by the three simple variables that combine to describe all colors and are known in the Munsell system as Hue, Value, and Chroma. NOTE: The Regular Format, 1954, contains the following seven charts: 10R, 2.5YR, 5YR, 7.5YR, 1OYR, 2.5Y and 5Y. This collection is the same as used by the U. S. Soil Conservation Service in the United States. The following additional charts are available where required: 7.5R-slightly more red than 10R, used in most tropical and semi-tropical lands. 5R -slightly more red than 7.5R, used in tropical lands, particularly Australia, Africa and South¬east Asia. /I Chroma-a selection of near-gray colors for hues from yellow through green and blue, for sub¬merged soils, 28 colors on value levels 4/ through 7/.
