Minimalist graphic visual long shadows design prompt

Generate a minimalist graphic visual with a strong memory point around any theme: the image first reveals a large, bright, clean, almost textureless high-brightness color field. The thematic content is broken down into many very small-scale real silhouettes, symbols, or partial objects, sparsely scattered in the wide white space, maintaining a clear distance from each other to let the sense of vastness be the protagonist. Each small subject must cast an exaggeratedly elongated dark shadow, with the shadows crossing the image in a uniform diagonal direction, much longer than the subjects themselves, forming rhythmic lines more striking than the subjects; locally, a projection of a massive structure can cut in from the edge, showing only a heavy dark shape and a few regular light-transmitting slits, creating a scale contrast and an urban-like sense of oppression. Colors are extracted from the material, emotion, and cultural semantics of the future theme itself, maintaining the role relationship of 'large areas of clear and bright base color, minimal high-contrast dark structures, and tiny thematic color accents.' The overall image remains bright, clean, airy, with clear color gradations, avoiding grayish, dirty, retro yellowing, or muddy color mixing. If informational text appears, it should act as a calm visual weight: a group of bold, black, tightly arranged large characters placed near one edge to create firm vertical pressure, while a few small words are distributed in corners or at the bottom with thin spacing, as restrained, precise, and leaving large open spaces like public signage. The overall completion should look like a strictly composed commercial art image; although the subjects are small, the shadows are huge, creating a strong sense of sunlight, order, isolation, and redefinition between real objects and abstract color fields.
