This composition is a good example of showing complementary colors because it is showing the complementary color set yellow/purple being across from each other and since they are next to each other the two colors I think tend to stand out more and appear to be more bold rather if they were not next to each other at all.

This composition shows a good example of a tetrad forming together from the color wheel. A tetrad is a group of four colors taken together from the color wheel usually including 2 complemetary colors. The tetrad of colors shown here are red, blue, green, and orange. Where red and green is one set of complementary colors and blue and orange are the other set.

This composition is a good example of showing the triad of primary colors which are red, blue, and yellow.

This composition displays monochromatic colors which is a color showing the different tones of itself in addition to the ground hue. Here the green is seen as a solid green but then it also shows itself in different spots where it is either lighter or darker.
