Why should the brush be washed before taking another watercolour?

Answer and explanation

Correct answer: To keep colours clean

The governing concept is preventing unintended colour contamination. If pigment from the previous colour remains in the brush, it mixes with the next colour and changes its intended hue or value. Washing the brush before loading a new colour therefore keeps the mixture clean, making option A correct. Rinsing does not make bristles stiff, dry paper immediately, or serve to colour the palette surface.
