This piece is all about subtile contrast. I like to use translucent oil colors on the metal panels as they let the reflective metal shine through. When viewed in person, it creates the illusion of depth, especially when contrasted with opaque paint colors. I have been working this out a little differently in each painting. In the sky, the reflective sheen of the metal is veiled by an undulating layer of oil paint. It contrasts with the hard linear edges that boldly glisten in the road.
