The notebook cover is designed by coding in p5.js. I use cheerful colors, such as a yellow background. Positive colors are excellent. Yellow is associated with power, self-esteem, and communication. Light yellow makes people more pleasant and enthusiastic, which is my ideal color because it can increase attention and memory. Orange is a warm, attractive, and pleasant color. It evokes social contact, happy connections, and happiness. It has a strong emotional presence and promotes extroverted behavior, making it a wonderful color gathering space, promoting interaction and relationship building. Although the green and blue hills are cool colors, they symbolize nature and the natural world. Because of its strong connection with nature, green is often considered to represent peace, good luck, health, and jealousy. Green is often used for decoration because of its calming effect. Blue is like the color of the sea and sky; it usually symbolizes peace, stability, inspiration, or wisdom. It can be a calm color, a symbol of reliability. The shape of the middle like a flower unfolds outward, just like fireworks, also represents liveliness and happiness

At the same time, based on the 2D images, I challenged myself to experiment and innovate by coding in p5.js and adding animation effects.
