The Munsell Soil Chart is how we identify and categorize different soils. It is broken down into three aspects of the soil coloration, the Hue (or the basic color of the soil, i.e. red, yellow, green, blue, purple), the Value (or the lightness or darkness of the coloration), and the Chroma (or the saturation/ intensity of the color). 

 

 The Soil Texture Dichotomous Key is a battery of questions one answers about a soil while examining it when wet. This helps to further identify it. An example of a soil texture dichotomous key is here.

This is an example of a soil texture diagram:
