With her screen print "Sun Mad", Hernández brought awareness to the injustices faced within her community. She created "Sun Mad" in 1982 after learning that her hometown in Dinuba, California had “polluted water and who worked in an environment contaminated by pesticides.” Depicted in "Sun Mad" are a bright red background, a “yellow disk of sun,” and a red bonneted skeletal figure holding a basket of grapes. To add, the skeletal woman is smiling and wearing a white shirt with two black stripes on the sleeves. Below the skeleton are the words, “Sun mad raisins, unnaturally grown with insecticides - miticides - herbicides - fungicides.” Here the words “sun mad” are printed in a bold, yellow font, while the rest of the font is in a smaller and finer white. Additionally, Hernández's palette consists of cool and warm colors; for instance, the green grapes and leaves, as well as the brown basket and skeleton’s hair, illustrate cool colors. On the other hand, the red background and bonnet plus the yellow disk and “Sun mad” logo illustrate warm colors. The artwork’s surface is flat but contains bright, expressive colors alongside a recognizable symbol; here Hernández offers deep messages within the screen print.
