Question

'Chroma' variables in determination of soil colour is represented by

• A. Spectral region of the colour
• B. Whiteness of the colour
• C. Relative brightness of the colour
• D. Relative purity of the colour

Hint:

Munsell soil colour system:
- Hue: Spectral region (e.g., 10YR).
- Value: Brightness (lightness/darkness).
- Chroma: Purity (intensity/saturation).

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
This question tests knowledge of the Munsell soil colour system.

Step 2: Detailed Explanation:
In the Munsell colour system, chroma represents the relative purity of the colour (D).
It indicates the intensity or saturation of the colour.
Higher chroma means more pure and intense colour.
Other variables:
- Hue (A): The spectral region of the colour (e.g., red, yellow).
- Value (B): The whiteness or brightness of the colour.
Thus, chroma represents the relative purity of the colour.

Step 3: Final Answer:
Thus, chroma represents the relative purity of the colour, which corresponds to option (D).
