The design inspiration comes from the palace gate and the palace gate head. The unique form of the pepper chart head is applied to the design of the ring on the back of the mobile phone case. The overall design model is divided from the palace gate and the color matching style of the Forbidden City. When extracting the elements of the Forbidden City, the shape of the pepper chart is simplified, so that the design style is not too traditional, and it also implies that the beast head ring is ominous. The height of the shop head should be reduced as much as possible to prevent the excessive back shape from increasing the thickness of the mobile phone, thereby improving the user experience. In terms of color matching, in addition to the common Forbidden City red, you can consider jade white, agate jade, ink black and other colors, with gold decoration, which can also show the royal color style. Don't ask for publicity, just for dignity.
