I hadn't noticed…

I have been preparing some paper for drawing for a new picture book. By the look of things, I need to introduce some colour. But I love Payne's Gray. Come to think of it, outside was like this today. This looks like any window would have looked today. I should pay more attention when it counts, because this was an afterthought.
