So the first image you see is carrots that are peeled and lined up. This is monochromatic because you can see the difference in the shade of orange and this is caused by the shadow of the carrots. Second image you see next is the desert that is purely saturated to show the contrast between the sand and the sharp blue sky. This is complementary because blue is complement to orange. The last image is analogous because the red, orange, and yellow is together just like in the color wheel.
I really like the photos you chose. Especially the complementary picture. I can clearly see the color between orange and blue. As for the monochromatic i can see the shadow of the carrots that makes both orange visible. As for the analogous it matched the color on the color wheel well.
