Shale description. The Munsell color system uses a numerical scale to identify color, rather than "traditional naming conventions" which can be easily misinterpreted. The system helps create uniformity in the way a color is described and differentiated.

The only difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. Both are made of ancient mud.
