My challenge to convey whites in watercolour in Barry’s Tuesday watercolour class was to maintain the relationship between core and cast shadows, while developing the shapes of the white containers in contrast to the brightly coloured apples. As we observed, when bathed in direct light, some of the apples were lighter than the adjacent white objects. Later in the week I re-visited the exercise, using red apples, white objects and a white cloth trimmed with a red stripe. I randomly touched very pale pink, yellow and blue into the bright fabric area before I drew in the shadows. It’s virtually invisible, but does help the white cloth glow. Once again I finished up with soft charcoal pencil.
