Why should hands be washed after working with acrylic colour?

Correct answer: To remove paint residue from the hands and maintain hygiene

The governing safety concept is personal hygiene after handling art materials. Washing the hands removes paint residue and helps prevent it from reaching food, drinks, the eyes, or the mouth. The brush must be cleaned separately, and handwashing cannot brighten paint or dry paper. Therefore option C correctly explains the reason for washing hands after acrylic work.
