What is the Munsell scale?
Value indicates the lightness of a color. The scale of value ranges from 0 for pure black to 10 for pure white. Black, white and the grays (as shown in figure 2) between them are called “neutral colors”.

-2- Page 4 fractions. Thus the notation for a color of hue 5YR, value 5, chroma 6, is 5YR 5/6, a yellowish-red. The notation for a color midway between the 5YR 5/6 and 5YR 6/6 chips is 5YR 5.5/6; for one midway between 2.5YR 5/6 and 5YR 6/8, it is at 3.75 YR 5.5/7.
What color is top soil?

How do you write the color Munsell?
In recording a color by Munsell notation, the symbol for HUE is written first (Fig. 2), and is followed by a symbol written in fraction form, the numerator indicating the VALUE and the denominator indicating the CHROMA (H V/C). For instance, a sample which is 5.0 Red in HUE, 5 in VALUE and 8 in CHROMA is written 5.0R.

What is the Munsell Soil Classification system?
Munsell’s Soil Classification System has been the industry standard for more than 60 years, aiding in the management and stewardship of our earth’s natural resources. Munsell Soil Color Charts are a quick and affordable way to assess soil types in any given area.
