where to fill it and where to say this doesn't need another line or another pail of colors. It's saying it in space. Spray painting Surprisingly few artists used the spray gun technique to create large expanses and fields of color sprayed across their canvases during the 1960s and 1970s. Some painters who effectively used spray painting techniques include Jules Olitski, who was a pioneer in his spray technique that covered his large paintings with layer after layer of different colors, often gradually changing hue and value in subtle progression. Another important innovation was Dan Christensen's use of a spray technique to great effect in loops and ribbons of bright color; sprayed in clear, calligraphic marks across his large-scale paintings. William Pettet, Richard Saba, and Albert Stadler, used the technique to create large-scale fields of multi-colors; while Kenneth Showell sprayed over crumpled canvases and created an illusion of abstract still-life interiors. Most of the spray painters were active especially during the late 1960s and 1970s. Stripes Stripes were one of the most popular vehicles for color used by several different color field painters in a variety of different formats. Barnett Newman, Morris Louis, Jack Bush, Gene Davis, Kenneth Noland and David Simpson, all made important Series' of stripe paintings. Although he did not call them stripes but zips Barnett Newman's stripes were mostly vertical, of varying widths and sparingly used. In Simpson and Noland's case their stripe paintings were all mostly horizontal, while Gene Davis painted vertical stripe paintings and Morris Louis mostly painted vertical stripe paintings sometimes called Pillars. Jack Bush tended to do both horizontal and vertical stripe paintings as well as angular ones. Magna paint Magna, a special artist use acrylic paint was developed by Leonard Bocour and Sam Golden in 1947 and reformulated in 1960, specifically for Morris Louis and other stain painters of the color field movement. In Magna pigments are ground in an acrylic resin with alcohol-based solvents. Unlike modern water-based acrylics, Magna is miscible with turpentine or mineral spirits and dries rapidly to a matte or glossy finish. It was used extensively by Morris Louis, and Friedel Dzubas and also by Pop artist Roy Lichtenstein. Magna colors are more vivid and intense than regular acrylic water-based paints. Louis used Magna to great effect in his Stripe Series, where the colors are used undiluted and are poured unmixed directly from the can. Acrylic paint
