This is my Color Studies assignment. It shows four different car illustrations that were done on Photoshop. The four illustrations show a version of monochrome, complementary, split complementary, and tetrad. 

This first one shown is the monochrome version. I used red as the main color. 

The second one shown is the complementary. The two colors that were used here were red and green. I decided to give it the same sky design like the monochrome, but with the speckles being green instead. 

The third one shown is the split complementary. The colors that were used here were red, blue, and brown. Same sky design like the last two, just different color use. 

The fourth one shown is the tetrad. The colors that were used were orange, green, yellow, turquoise, and purple. This one was the most different design than the others due to the new sky look.
