Abstract Diesel Rainbow 1 . An inspiring design made from a negative situation in to a positive piece of art work. A unique Serial Karnage design by MC Seph. Comments: This is from a diesel spillage that was near a roundabout close to my home, it wasn't the greatest photo but I managed to manipulate it into something resembling a marble pattern of some type. I have made a couple of versions of it. They are mainly different shades of blue and green but you can see the rainbow effect clearly in each one.
