Design initial concept and style frame for product promotion animation.The main color of this product is a combination of frosted gray and four colors of red, yellow, blue and green, so the color wheel I used in my design is based on these five colors. The concept I designed is to use colored lines to guide the feeling of inspiration in the dark, so the whole camera will follow the movement of the four colored lines of red, yellow, blue and green, and the whole picture of the product will gradually appear in the dark background.
