This set of gouache adopts independent packaging, and stresses the flat design style via the pure color, simple patterns and texts. The transparent gouache cups in a matrix layout and the openingsĀ at the bottom jointly highlight the color harmony between the gouache and the box, while enhancing interaction. Besides, bevel buckles around the box conduce to the geometric illusion of lower height, the effective sealing and stability. Additionally, infrequently-used paints are paired in bevel cups to fully utilize inner space and expand the area for color picking, reflecting the humanized design.
