In 1997, Mark Grotjahn began his well-known butterfly paintings, precisely rendered abstractions defined by thickly applied paint emanating in a fan-like pattern to the edges of human-scaled canvases. The works explore shifts in perspective and spatial illusion: vertical bands radiate out from two points at the center of the canvas while the density of the paint belies the illusory flatness of the surface. As the title details, Untitled (Blue Painting Light to Dark X) (2006) is from a cycle of ten canvases painted in shades of blue. The dark blue of this tenth monochrome shimmers in the grooves of hundreds of fine brush marks. However, a subtle yet vibrant orange underpainting at the center and edge of the canvas disrupts the plane of color and creates the shifting ground and foreground illusion as well as a dynamic play between symmetry and asymmetry originating from the points of convergence.
