The constant in Mitchell's working was her open commitment to beauty and deep love of the physical acts of painting. Whether materializing joyous memories or painful ones, or the ambiguous shades in between, the love of beauty and of painting remained constant. So, too, did the visceral physicality and the visible openness of structure that so directly, and vulnerably, sought to ravish the viewer's eye, drawing it into complicity with the profundities that exacerbated the painting's surface - Klaus Kertess (Klaus Kertess, Joan Mitchell, New York, 1997, p. 41)
