Painter Robert Ryman was born in Nashville in 1930. Giorgio Morandi, also a painter, was born in 1890 in Bologna, Italy (he died there in 1964). Ryman paints abstractly, Morandi representationally, but the two share an attraction to a muted palette. Hung side by side in Kohn Gallery, their works fit together so nicely that, with a quick glance, you can imagine they were made by a minimal father and his more minimal son. But if you’ve read artist William Pope.L’s memorable meditation on the obsession of Ryman, a white artist, with the color white, it’s hard to look at his monochromes without thinking of these lines: “Robert Ryman is the great white painter ... he has no time for anything that intrudes or distracts from his greatness. He’s too busy being great.” 1227 N. Highland Ave., Hollywood; through Oct. 31. (323) 461 3311, kohngallery.com.
