Design and Transmission

Our basic principles to design deepin: Simple, beautiful and content first. Hope everyone will feel amazing, smooth, fresh and distinctive when using deepin.



The core for icon design is to allow you to quickly identify and memory. So we disassembled the design into three parts: Shape, color and symbol.

Taking Deepin music icon for example, we visualize music by the orbital vinyl record, express the good mood to listen to music by green, and show the abstract music by staff notation.


Newly added system sound effect, and we pour musical elements into common operations. The combination of action and music enriches each operation with a bit more fun.

Taking the sound effect of Deepin Screenshot for example, it catches the joy to capture a picture every time, just like taking a picture of beautiful scenery by camera.
