Design a simple and elegant logo for 'Global Harmony,' a company that hosts AI-powered pet image contests and envisions a harmonious world where humans, animals, and AI coexist peacefully. The logo should feature a clean, minimalistic design with elements symbolizing unity and balance, such as interconnected circles or abstract representations of humans, animals, and AI. Use a calm color palette with soft blues, greens, and earth tones to convey peace and inclusiveness. Ensure the design is modern and professional, reflecting the company's mission of harmony and innovation. --ar 1:1 --niji 6
