The third botanical illustration features Indigo Bush, Psorothamnus schottii. This design was tricky in terms of color. It’s difficult to capture the blue-purple of the Indigo Bush flower. It’s even more difficult to print the color in CMYK! And depending on the paper, the colors appear either too dark or muddied.
Representing the androecium was also challenging (see our article on Indigo Bush details for a list of botanical terms). The artist was inspired by the lines of Erté in drawing the filaments.
