- Consider the following notation: The colour of soil, as per Munsell notation is denoted as 5Yr Study critically, the following explanations of this notation:
- 5 Yr denotes ‘hue’ of the colour wher Yr means yellow-d the gigure 5 indicates that the contribution of yellow low-d, the figur 5 indicates that the contribution of yellow colour to the soil is 5 times mor than that of red colour.
- The figur 5 in is the value of the colour which indicates that the colour is visually midway between absolute white and absolute black.
- The figur 6 in denotes the ‘Chroma’ of the colour. It shows the chroma is in the 7th place from 0 (including 0) in the scale of 0 to 20.
