ZERO&NINE has created a comprehensive theme for the Lenovo Lemon series smartphones, including icon design, widget design, related interface design, and phone back cover design. The main visual element is the lemon, abstracted into hexagons, with extended designs for related graphics.

Since the Lemon series is positioned in the mid-range price category, and the screen performance may be less robust than flagship models, the design intentionally enhances the vibrancy of colors. The use of high-purity colors aims to make the screen appear more vivid.
