What may be a technical cause of small bubbles in a coloured wash?

Answer and explanation

Correct answer: Whipping the mixture too rapidly

The governing concept is avoiding unnecessary air incorporation during paint preparation. Whipping or stirring a colour mixture too rapidly traps air in the liquid, and those air pockets can appear as small bubbles when the wash is applied. Mix gently and allow the mixture to settle briefly before painting. Colour lightness and brush cleanliness do not create bubbles by themselves, while tilting paper mainly changes flow direction.
