Color, like music, is a feeling. The three attributes of color are like scales in music. They can be used to maintain the order among various colors and form a hue circle that is easy to understand and convenient to use. When we "mix" together, this unit is divided into three parts: 1. Color Magician, 2. See who is the best, 3. I am the best at teasing "colors". The interdisciplinary aesthetic course is connected to the natural realm of aquatic plants. The nature teacher introduces the growth patterns and different appearance characteristics of aquatic plants; the art teacher introduces color science and techniques of different media. The basic principle of the Impressionist painting technique is color decomposition. Different solid colors are juxtaposed on the painting paper, allowing the viewer to reconcile them according to their own vision. Finally, the pointillism painting characteristics of the Impressionist master Seurat are used to complete the watercolor point painting of aquatic plants.
