Prompt: We needed to design a city logo that based the concept on Yichang's existing city logo but added a star to the letter I. The existing Yichang city logo is \"Yi\" composed of \"U\" and \"I\", smile elements, exclamation points, and hyphens. The graphic is based on the pinyin \"Yi\" of the word \"yi\", and the whole design is designed with round and lovely strokes. Among them, the Pinyin letters are transformed into smiling faces, exclamation marks \"!\" and circular elements. The color matching is also very consistent with this cute and round logo graphic, using a total of four bright colors of \"red, yellow, blue, and green\"; different colors represent vitality, nature, future, diversity and enthusiasm respectively. The entire logo represents the harmonious coexistence of man and nature, man and humanity, man and technology, man and city, man and the future. The logo as a whole is intended to create a diverse and dynamic city image. The stars are a symbol of Yichang's future and technology, because Yichang is a city with advanced infrastructure and strong innovation capabilities. The star also represents the light and warmth of Yichang, a city full of energy and youthfulness. The logo color is purple, which symbolizes mystery, creativity and nobility. The logo font is simple, modern and matches the logo style.
