HC is an industrial company from Hunan. Within 11 years of development, HC requires three logos for its three different ranges: control system, mobile machinery and electronic control solutions. I have designed the three logos based on a series of shapes. The colorful geometric shapes represent power. The black circuitry represents sensor and intelligence. The two elements together shows the combination of power and intelligence, which are also the keywords of HC's service. The selected colors are modern, technical and unique in the industry.
