I recently taught a ten week drawing course and where we were working mostly with pencil and charcoal. One week I introduced a small bit of colour by asking the learners to use ink with charcoal.
I noticed some relished the work with the inks but a few were reluctant, only ‘tinting’ small areas of the drawing as an afterthought rather than a feature of the drawing. As the sessions continued we used more colour including one session using pastels to draw brightly coloured flowers. The colours were vibrant many of the learners enjoyed using these colours, layering them, darkening them and smudging them to get an array of colours not always true to the real flower.
