Ray L. Burggraf (born 1938) is an artist, color theorist, and Emeritus Professor of Fine Arts at Florida State University. According to Roald Nasgaard, Burggraf's paintings exhibit "visual excitation...pulsating patterns, vibrating after-images, weird illusionistic spaces, multifocal opticality, executed with knife-edge precision...crisp and elegant and radiant with light." From a historical perspective, Burggraf's work is "nature evocative...reach[ing] back to the modernist landscape tradition of the Impressionists and of Neo-impressionists like Seurat, who, in the late-nineteenth century immersed themselves in the color theories of Chevreul and Rood" (Roald Nasgaard; former Chief Curator, Art Gallery of Ontario, 2006).
