Munsell Rock Color Book

Munsell’s Rock Color Book provides durable, portable charts to accurately classify and evaluate rock color samples in the field. These charts help geologists and archeologists communicate color more effectively by cross-referencing ISCC-NBS (Inter-Society Color Council-National Bureau of Standards) color names with unique Munsell alphanumeric color notations for rock color samples. The rock color chart here is revised from the previously published Geological Society of America (GSA) Rock Color Chart.

Munsell Rock Color charts are sturdy enough to evaluate samples where you need them most – out in nature. Charts can be used to evaluate rock color wet or dry and for medium, fine, or coarse-grained rocks. Although your Rock Color Chart is made to be cleaned and can endure rugged, real world conditions, damage and fading may require periodic replacement. Remember, it’s always better to look at old rocks with new charts than the other way around!
