The word 光彩 is formed by combining the character 光 (guāng), meaning "light" or "radiance", with the character 彩 (cǎi), meaning "color" or "splendor". It is a conceptual fusion where the brilliance of light merges with the vividness of color to create a single, unified idea of radiant and brilliant beauty. This formation visually and semantically suggests something that shines with a luminous and colorful brightness, often used to describe both literal luster and metaphorical glory or honor.
