Vertical Four Seasons Chinese Characters with Material Transitions on Black AI Image Prompt

Pure ink-black with a deep blue solid background (near-pitch-black late-night color, no people, no scene), four oversized Chinese characters “春夏秋冬” arranged vertically in the center, from top to bottom, vertically centered, with extremely tight letter spacing; the strokes of the four characters connect directly end to end, uninterrupted in the middle, without any gaps and without independent decorative elements; each of the four characters retains its own seasonal material, and the material naturally gradients along the character flow at the junction of adjacent characters, continuous and unbroken, with a transition band about one stroke length: ① The top “春” character is in semi-cursive script with tender sprout green plant texture, gradient from tender green to cyan-green, strokes have new-leaf fuzz, with faint pink petal halo inside the strokes; the bottom final stroke of 春 extends downward, tender green gradually deepens, fuzz fades, emerging jade-green water sheen, like spring water first rising, naturally transitioning into “夏” — the transition band is the color flow of spring water turning into summer waves; ② “夏” is in running script with lotus-leaf blue-wave texture, gradient from deep jade green to lake blue, strokes have water-surface shimmer highlight patterns; the bottom final stroke of 夏 continues downward, blue water sheen gradually fades, golden warm color rises, water shimmer transforms into golden leaf veins, like late summer turning into autumn, water light becoming gold, naturally transitioning into “秋” — the transition band is the warmth of summer water reflecting autumn sun gradually emerging; ③ “秋” is in running-cursive script with maple-leaf and golden rice texture, gradient from golden yellow to orange-red, strokes have leaf-vein patterns and rice grain texture; the bottom final stroke of 秋 extends downward, golden yellow and orange-red gradually cool and fade, leaf-vein patterns turn into fine ice-crystal textures, like autumn ending and entering winter, fallen leaves condensing frost, naturally transitioning into “冬” — the transition band is golden leaves gradually dyed frost-white; ④ The bottom “冬” is in semi-cursive script with ice-snow and ice-crystal texture, gradient from ice blue to pure white, hexagonal ice-crystal patterns inside the strokes, frost-snow fuzz on the edges; the four characters uniformly have dark outlines, clearly emerging from the black background, material gradients smoothly blend, no boundaries, uninterrupted in the middle; the image contains only these four connected vertical Chinese characters, no people, no scene, no petals, lotus leaves, maple leaves, snowflakes or any independent elements, pure text layer convenient for later cutout; overall temperament: the four seasons flow from top to bottom, spring birth, summer growth, autumn harvest, winter storage, materials naturally change, integrated as one, grand and recognizable.
