I like this work. I needed to know how it was done. I really couldn't enjoy it till I had some of the methods figured out. Below is a quote from a website. Can't remember which one. There were many!
Terry Rose is a painter whose works are the product of both careful planning and chance. His latest and best-known works are made using a wet-on-wet technique developed after arduous experimentation. Rose coats a surface with wet varnish, then drops in oils, inks, mirror pigments, and enamels, and lets the pigments react with the liquid medium. The chemical reactions create the final image on the work, which appears to be a collection of colors bleeding, blurring, expanding, or sliding around the work’s surface.
