Among the rare things John Derian collects, and that his fans love, are vintage colour studies created by artists and students. Now he shares twelve of the best in this irresistible themed calendar.

There are watercolours and oils, swatches and colour wheels, all in the most pleasing hues and gradations. It's as if each month takes you inside the mind of an artist-but also back in time, in that singularly evocative way that makes Derian's work unique in the world of design.
