Diffused light and whitespace visual design

Generate a visual design centered on diffused light sense and information whitespace around any theme: let the subject first be translated into two or three large-scale, edge-softened translucent color mists, overlapping, interspersing, and slightly misaligned in the middle of the frame, forming a main visual like a spreading halo, rather than a clearly outlined physical illustration; one mist carries the strongest emotional energy of the theme, with the largest area and most saturated color, another mist serves as an auxiliary flow direction, and the third layer serves only as a faint air background color, allowing the visual to slowly manifest from large areas of blank space. The background remains high-brightness, clear, clean, with a sense of ventilation and soft paper grain, with texture like fine printing noise covering the entire frame, but without creating a dirty, aged, or grayish-yellow feel. Colors are extracted from the theme's own material, season, brand, or emotion, mapped as a bright base color, emotional main color, auxiliary warm/cold colors, a small amount of clear emphasis colors, and dark information text; maintain the relationship of large areas of light base, small amounts of high-saturation luminous colors, soft transitions, and clean color scales, so the overall presentation has a bright, light, dreamlike but orderly temperament. If text appears, it should participate in the composition like design exhibition information: a small number of oversized titles scattered at the top or edges to form a static center of gravity, small explanatory text using narrow line spacing, short paragraphs, and precise alignment to establish a reading rhythm, dark characters kept restrained, sharp, with plenty of breathing space. The composition avoids filling the elements, retaining obvious blank pauses, edge-cropped color mists, tiny symbols or markers as beats, making the thematic content like an abstract memory illuminated by soft light, rather than an ordinary decorative background.
