Why is it necessary to wash the brush before taking another colour?

Answer and explanation

Correct answer: To keep colours clean

The governing concept is preventing unintended colour mixing. Pigment left in the brush can contaminate the next colour and change its intended hue, brightness, or value. Washing and gently removing excess water keeps the new colour clean, so option A is correct. Cleaning is not intended to stiffen bristles, dry paint faster, or wet the paper; those effects do not explain the practice.
