What correction should be made if the lower colour lifts while applying a glaze over a dry watercolour layer?

Correct answer: Use less water and light limited strokes

A glaze is a transparent layer placed over a dry layer, but excess water or repeated brushing can reactivate the underlying pigment. The controlled correction is to use a less-wet brush and apply the glaze with one or two light, purposeful strokes, allowing it to dry without disturbance. Option B is correct. More force or rewetting increases lifting, black changes value rather than solving the adhesion problem.
