"Duobaan" is phonetically close to "dopamine" in Chinese pronunciation. We tried to build a brand image constructing the atmosphere similar to the feeling conveyed by dopamine (a neurotransmitter that helps control the brain's reward and pleasure centers). Dopamine also helps regulate movement and emotional responses, and it enables us not only to see rewards, but to take action to move toward them. We took simple color blocks as fundamental elements. By way of composition method, we regularly arranged these color blocks into the form of "D" which serves as the initial of both "Duobaan" and "Design" ("design-driven" hotel).
