Founded in 1995, Bull, as a "specialist in safe electricity use", has over 1.1 million offline outlets and has participated in formulating 93 national and industry standards. With the wave of smart homes, Bull's product image is in urgent need of renewal. Centered on the "color strategy", KHT injects green into Bull—a color symbolizing safety, harmony and vitality, echoing the concept of green development, strengthening the perception of "smart life", and building a unique brand color gamut system. The product system is divided into three categories: household, business travel and engineering, covering different grades and scenarios. The design language returns to points, lines and planes: household products feature soft lines, business travel products have concise lines, and engineering products have a sturdy style, achieving visual unity and clear transmission of attributes. This upgrade not only reshapes the visual image, but also connects the new generation of consumers, helping Bull establish a more standardized, international and approachable new brand image in the smart era.
