Ulsan Hospital, founded on the long-standing philosophy of “Helping others and saving lives together,” has redefined its identity by redesigning its Hospital Identity (HI) and renewing its color and signage system to enhance patient-centered care and service quality. The new HI visualizes the hospital’s initials “UMC” using the motif of an electrocardiogram graph, symbolizing a heart that beats 24/7 and reflecting the hospital’s specialization in cardiac care. The color plan was carefully designed to provide psychological stability and trust for patients, using warm, low-saturation tones in public areas to ease tension, natural and soft colors in outpatient areas to evoke comfort and vitality, and calm whites in emergency spaces to promote a sense of cleanliness and support efficient medical operations. This comprehensive design approach visually embodies Ulsan Hospital’s identity and compassionate philosophy, creating a healing environment that thoughtfully supports both patients and medical staff.
