Why is it useful to keep two water containers while working with poster colour?

Answer and explanation

Correct answer: One for initial rinsing and another for clean final rinsing

The governing concept is prevention of colour contamination. One container can remove most of the previous pigment from the brush, while the second provides a cleaner final rinse before a light or white colour is used. This keeps the next colour purer and reduces muddy mixtures. Therefore, option A is correct; the other choices do not describe a normal or safe brush-cleaning practice.
