Flat illustration is a visual style that abandons complex light and shadow, perspective, and three-dimensional effects, with simplicity at its core. It uses smooth and clear lines to outline shapes, filled with bright and pure color blocks, and has no elements like gradients or shadows that enhance a three-dimensional feel.

It focuses on graphic expression, often simplifying object details to highlight the theme, and has a brisk and intuitive style. Widely used in UI design, posters, children's books and other scenarios, it can convey information quickly. Meanwhile, its minimalist aesthetics adapt to various communication carriers, featuring both practicality and visual appeal.
