Why should a clean brush not be too wet during blending?

Correct answer: It may release excess water and create blooms

During blending, the brush should carry only enough moisture to soften the transition. If it is very wet, excess water leaves the bristles and pushes pigment outward, producing blooms, tide marks, or pale uneven patches instead of a controlled blend. Therefore option B is correct. A wet brush does not make paint opaque, shrink paper, or dry the colour immediately.
