Which choice is better if colour lifting is planned later in an area?

Correct answer: A less-staining, easily liftable colour

Colour lifting works best when the pigment remains comparatively near the paper surface and can be loosened with clean water and a controlled brush. A less-staining pigment therefore gives the artist a better chance to create highlights or corrections later, making option D correct. Strongly staining colours and several dark layers are harder to remove, while heavy rubbing damages the paper rather than improving liftability.
