Which method is useful for creating a gradation with acrylic colour?

Correct answer: सफेद या गहरे रंग की मात्रा को धीरे-धीरे बदलना | Gradually changing the amount of white or dark colour

The governing concept is gradual change in value or colour intensity. A gradation moves smoothly from light to dark, or from a weaker mixture to a stronger one, so the amount of white or dark colour should be changed in small steps. Unrelated bands and unblended patches interrupt continuity, while scratching dry paper is a surface-treatment method rather than a way to form an acrylic colour transition.
