For the first color composition, I chose a monochromatic scheme of only shades of orange. For the second, I chose a complementary scheme of red and green. For the third, I chose an analogous scheme of blue and green. For the fourth, I chose a monochromatic scheme of only shades of purple. I think the most successful color composition of these four is the complementary one, because red and green together is a classic combination, and one I think a lot of people love!
