Which precaution is most necessary for clean mixing of primary colours?

Answer and explanation

Correct answer: Use a clean brush and palette

The governing concept is pigment purity during colour mixing. A clean brush and palette prevent leftover pigment, dust, or water from entering the new mixture, so the intended colour remains bright and predictable. Option B is correct. A dirty brush can contaminate the mixture and make it muddy; adding black is unnecessary and changes value, while scratching dried paint does not ensure a clean mixture. Washing and wiping tools between colours is good practice.
