极简典礼感信息海报设计框架

Construct a minimalist ceremonial information poster around any theme. At first glance, it must be a precise centering of the main title and three theme symbols within a large area of warm white space, creating a solemn counterpoint: the theme provides core names, participants, or keywords, transformed into a large thin-stroke title at the top, a set of recognizable abstract symbols in the center, and solid color blocks on both sides; semantics change but the order remains constant. The image retains a high proportion of white space, a vertical central axis, top and bottom partitioning, and a sense of pause from thin black horizontal lines; all elements are restrainedly arranged like an exhibition catalog or an international organization yearbook. The main text uses high-contrast thin serifs or equivalent glyph structures, with open counters, thin strokes, sharp terminals, and spacious rhythm, maintaining a slender skeleton, wide letter spacing, clear recognition, and calm breathing when replaced with any writing system, rather than copying a specific Latin typeface. Colors are extracted from the theme into two high-purity representative colors as hard-edged blocks; the middle symbol uses only black lines and a few solid geometries; the background is a slightly paper-textured warm white, avoiding gradients, shadows, and decorative textures. The bottom places the subtitle and small explanatory text with a lower center of gravity, and the footer's three-point miniature information presses against the edges, forming a contrast where the grand theme is tamed by museum-style white space; failure symptoms are elements becoming full, colors becoming busy, fonts becoming thick, icons becoming realistic, or the poster losing its cool ceremonial order. —————— Set the theme as 'City Public Library Open Day' for the main poster of a public cultural institution event: use indigo and cinnabar red as the two high-purity block colors, abstractly represent open book pages and door arches with black lines in the center, and the symbol group falls steadily from below the title along the vertical central axis; the main title is placed in the center of the upper half, with the subtitle and date forming a sparse two-level information hierarchy below, retaining a large area of warm white space and thin black horizontal line pauses; the aspect ratio is vertical 3:4.
