Katharine Beisner has pieces that play with the eye and color. Some artists find it more appealing to use classic shapes that people can pinpoint and describe rather than using abstract shapes. Katharine does this. By adding color of the same family she creates a piece that looks more flat and uniform. By having colors that aren't necessarily from the same family, she creates more of an eye interesting piece. The green and earth tone aren't in the same family but they can be found in nature places together which is why this piece works. If she would have used any other colors, the piece would not have flowed the way that it does.
