Answer:
Minimum value of tone varies from object to object
Step-by-step explanation:
Tonal value is a very significant term in the case of drawing. It tells about the lightness and darkness of anything in a picture. Tonal value adds life to a drawing But the Exact amount of it is to be determined. We have to see the minimum level up to which such value can be added.
This level depends upon the object being drawn.
To create a successful painting it is advisable not to add many colors into it. Keep it as much as simple as u can. Apply any color with the minimum amount of water and then add water afterward to adjust the tone.
