Acrylic No. 7 marks Fanny Sanín’s permanent transition from the gestural painting style of her pre-1969 works to geometric abstraction,  the ordered, linear, and symmetrical style for which she is best known.

In 1970, after adopting acrylics as her preferred medium, Sanín painted a series of striped compositions including Acrylic No. 7. This large-scale painting boasts vertical bands of rich autumnal hues.

The composition demonstrates Sanín’s mastery of formal elements such as line, shape, and color. Acrylic No. 7 is both ordered and varied; simple and complex. Crisp lines guide viewers’ eyes up and down the canvas and provide clear demarcations between hues.

Variation in stripe widths and colors create a pleasing visual rhythm. The juxtaposition of cooler, receding tints—pale yellow and light green—and their warmer, advancing counterparts—bright orange and chocolate brown—give the illusion of balance and depth of field.
