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.
