Sam McKinniss's *Ghosts (orange and green)* (2015) is a luminous painting rendered in oil, acrylic, and aqua-leaf on canvas, combining warm orange and cool green tones to create a vivid, otherworldly atmosphere. McKinniss employs a bold, graphic sensibility reminiscent of pop art and illustration, lending the image a seductive flatness that hovers between representation and abstraction. The incorporation of aqua-leaf adds a shimmering, metallic quality that enhances the work's ethereal, ghostly presence.
