This Painter’s keys article offers some of Sara Genn’s tips on colour in a 30-minute exercise.

“For this exercise, commit to 30 minutes and a palette of six mixable colours, warm to cool, avoiding black. (Hint: mixing Phthalo Green with Alizarin Crimson, or Ultramarine with Burnt Umber make fabulous darker darks.)”
