Which precaution is necessary to obtain the cleanest secondary colours from primaries?

Answer and explanation

Correct answer: Use clean brushes and pure colours

The governing concept is colour purity during pigment mixing. A brush carrying residue from another colour, muddy water, or contaminated paint introduces unwanted pigments and makes the intended secondary colour dull. Using a clean brush, clean water when needed, and uncontaminated primary paints keeps the mixture closer to the desired hue. Black, dirty water, and all three primaries reduce clarity, so option A is correct.
