When the Scottish Gallery of Modern Art staged their F.C.B. Cadell exhibition two years ago, they painted the walls of the rooms in which the paintings were hung the same shade of lavender grey as Cadell used in his studio.
It seems the gallery is not unique in going to such lengths in their preparation, for in this video, Tracy Chevalier explains why she re-paints the walls of her study when she begins work on a new book - and her notebooks* are colour-coordinated, too. That short film was made when she was working on Remarkable Creatures, so an early 19th. century grey provided authenticity and inspiration, but I wonder what colour she has chosen for her current project, a novel which - as you can see here - will feature fruit trees.
*Speaking of grey notebooks, Persephone Books can supply you with a lovely one.
