The picture below is of an acrylic on paper painting, one foot square, framed and mounted, which is going into the Shades of Green exhibition at Vestry House Museum , Walthamstow, next week. This reproduction is poor, and has turned the violet of the original painting blue, but the image is none the worse for that.

The shade of green in question is open to debate: the image should really be Shades of Blue, but, hey, this is art we're talking about-get over it.
