手机壁纸和普通插画最大的区别,不是尺寸,而是「有没有地方放图标」。一张很好看的云海图,铺到锁屏上把时钟压在云朵亮部,时间立刻读不清;铺到桌面又被图标盖住主体。这 12 条提示词用同一片云海贯穿,按一天里的不同时段推进,同时把留白位置当成硬参数写进去,方便你直接对上锁屏和桌面两种用法。
先解决构图:壁纸的主体不能占满
竖屏壁纸的可用区域其实被系统切成了几块。锁屏顶部要给时间和大字日期留位置,底部要给手电与相机两个快捷入口留位置,中间才是主体能安心待的地方。桌面则相反,图标从左上往右下铺,画面中间偏下往往会被挡住。
所以写提示词时,先决定「留白在哪」,再决定「云海在哪」。这两件事定下来,颜色和光线才有意义。下面每一条都带了 9:16 与位置词,不建议删。
另一个容易被忽略的点是亮度。壁纸是长期停留在屏幕上的图,亮部面积大的图会刺眼,暗部面积大的图会让图标看不清。中低对比、云层边缘柔一点,实际用起来比高对比的「大片感」舒服得多。
清晨到正午:把光留在上方(01–04)
这四条都适合锁屏。共同点是天空占比大,云海压在画面下半部,时间文字有干净的底。
01 · 拂晓前的蓝灰云海
Vertical 9:16 mobile wallpaper, pre-dawn cloud sea seen from a mountain ridge, upper left third almost empty for the lock screen clock, soft [dawn color] gradient, low contrast haze, distant peaks as faint silhouettes, [mist density], minimal composition, fine grain, calm and quiet怎么用:[dawn color] 写 blue grey and pale rose,别写 purple,紫调在屏幕上会偏脏;[mist density] 用 thin 或 moderate 控制层次。上部留白要写 upper left third,写 top 会让模型只留一条窄边。
02 · 日出,云顶先亮
Vertical 9:16 wallpaper of a sunrise above a cloud layer, the sun still below the horizon, cloud tops edged in [warm highlight], the upper two thirds kept soft and open for clock text, deep blue shadow in the valleys, [lens character], tranquil mood, subtle atmospheric perspective怎么用:[warm highlight] 建议 pale gold;[lens character] 写 soft anamorphic glow 会有轻微的横向光晕。太阳别写 visible sun disc,一旦出现圆盘,锁屏时间就压不住亮度了。
03 · 上午的云隙光柱
Vertical 9:16 phone wallpaper, morning light shafts breaking through a high cloud deck onto a distant sea of clouds, subject anchored in the lower right, upper area washed with [pale sky tone], [ray count] visible beams, gentle falloff, airy negative space, painterly realism, no hard edges怎么用:[pale sky tone] 用 milky blue;[ray count] 写 three 或 four,写 many 会得到放射状的光斑。光柱方向要一致,都从左上方斜下,方向一乱画面立刻散。
04 · 正午的极简云边
Vertical 9:16 minimalist wallpaper, a single soft cloud bank along the bottom edge at noon, the rest of the frame a flat [sky gradient] with no detail, one small bird silhouette for scale, generous empty upper half, low saturation, smooth tonal transition, meditative and clean怎么用:[sky gradient] 写成 from pale cyan to warm white 这种两段式,单写 blue 会得到一整块死色。这条越空越好,别加山、别加飞机,一个小鸟剪影就够定尺度。
午后到夜晚:主体下移,给图标让路(05–09)
这五条更偏桌面壁纸。云海放在中部偏下,上方保留一段相对平静的区域,图标压上去也不至于完全盖住画面。
05 · 午后堆叠的云层
Vertical 9:16 desktop wallpaper, layered cumulus clouds stacked in the middle band, tops lit by [afternoon light], shaded undersides in cool grey, a narrow strip of clear sky at the very top, [cloud scale], soft edges, no sun, quiet afternoon atmosphere, medium contrast怎么用:[afternoon light] 写 low warm white;[cloud scale] 用 large slow forms,云团够大才有体积感。别写 dramatic,一加戏剧性云就变成风暴,和治愈系的气质正好相反。
06 · 黄金时刻的暖橘海
Vertical 9:16 wallpaper, a cloud sea glowing [amber orange] at golden hour, foreground ridge in dark silhouette along the bottom, mid frame filled with rolling cloud tops, upper fifth left quiet, warm reflected light, [contrast level], cinematic but soft, gentle vignette怎么用:[amber orange] 与 [contrast level] 决定成败,对比写 medium low 才不会把暗部压死。暖色面积大时容易过曝,可以在提示词里补 retained highlight detail。
07 · 日落逆光的云海剪影
Vertical 9:16 phone wallpaper, backlit cloud sea at sunset, cloud edges rimmed with [rim color], the sun hidden behind the horizon so the sky reads as one smooth field, foreground rocks as pure silhouette, upper third clear for widgets, atmospheric, restrained palette怎么用:[rim color] 用 thin coral light;关键是 sun hidden,写落日圆盘会毁掉留白。前景剪影要写 pure silhouette,带细节的前景会把视线拉到画面底部,锁屏上一片乱。
08 · 蓝调时刻的平流云
Vertical 9:16 wallpaper, blue hour over a flat layer of stratus cloud, sky in [blue hour palette], a faint gradient from deep indigo at the top to dusty teal near the horizon, no sun, [noise level] grain, silent and cool, wide tonal range kept gentle怎么用:[blue hour palette] 写成 indigo and dusty teal,别用 navy,navy 在 OLED 屏上几乎全黑;[noise level] 写 light。这条适合深色模式,图标是白色的,底色越沉越好读。
09 · 月夜与一条光路
Vertical 9:16 wallpaper, moonlit cloud sea at night, a narrow path of [moon reflection] running from the horizon toward the viewer, scattered stars only in the upper area, deep blue shadows, [star density], soft glow around the moon, still and dreamlike, low contrast怎么用:[moon reflection] 写 silver blue;[star density] 用 sparse,星点一多就像素材图。光路要写 running toward the viewer,否则模型会画成一条横在天上的带子。
极简、天气与视角(10–12)
最后三条不靠时间推进,靠「更少的元素」收尾。它们更适合作为整套壁纸的备选,或者给不喜欢画面太满的人。
10 · 深蓝渐变的极简夜
Vertical 9:16 minimalist wallpaper, near-black [deep blue] field with a single thin band of cloud crossing the lower third, one faint star, no horizon line, no landscape, smooth gradient with slight banding removed, [mood word], extremely restrained, suitable for dark mode怎么用:[deep blue] 用 ink blue;[mood word] 写 still 或 solitary。渐变最容易出现 banding,补上 no banding 这个短语,成图的过渡会干净很多,适合大面积铺屏。
11 · 雨后云隙,湿空气
Vertical 9:16 wallpaper, cloud sea just after rain, a single break in the overcast letting [cool daylight] through, wet haze softening the horizon, foreground grass beaded with water, upper half muted and empty, [saturation level], fresh and clean, natural color怎么用:[cool daylight] 写 pale silver;[saturation level] 用 low saturation,雨后的空气感靠低饱和加高亮度,不是靠加蓝。草叶上的水珠只写 beaded,别要求清晰水珠特写。
12 · 云层之上的平流视角
Vertical 9:16 wallpaper shot from above the cloud deck, endless cloud tops forming a soft horizontal rhythm, no land visible, a pale [high altitude sky] band across the top, [cloud texture], abstract and calm, minimal detail, subtle depth, meditative composition怎么用:[high altitude sky] 写 pale cerulean;[cloud texture] 用 cotton-like but soft。视角必须写 above the cloud deck 才有无边感,写 aerial view 常会带出地面和道路,治愈感立刻消失,云面也会变碎。
通用出图技巧
- 尺寸词写 vertical 9:16,别只写 phone wallpaper,后者经常给出接近方形的构图。
- 留白要指定方位与比例,upper third、lower fifth 这类说法比 leave space 明确得多。
- 治愈系的关键是低对比和柔和边缘,提示词里加 soft edges、low contrast、gentle falloff 三个短语就够。
- 云海不要写 storm、dramatic、epic,这些词会把画面推向风景大片,和长期看屏幕的需求相反。
- 锁屏用图把主体放在下三分之二,桌面用图把主体放在中部,两套别混用。
- 出图后先缩到手机尺寸看一眼,再决定要不要加细节,很多问题在缩略图上才看得出来。
常见问题
问:为什么壁纸导进手机后,上下被裁掉一截?
答:多数是比例不对。生成时明确写 9:16,拿到图后按手机实际分辨率等比缩放,不要直接拉伸。若必须裁切,从上下同时裁,保主体位置不变。
问:锁屏时间总是看不清,怎么调整?
答:问题在主体亮度,不在时间颜色。把留白区域的云写得更平、更暗,或者直接把主体移到下三分之一。也可以给留白区加一层 soft gradient,让白字有稳定的底。
问:同一片云海怎么做出成套感?
答:固定三个东西——视角高度、云层尺度、色温倾向,只改时间和留白位置。视角一变,十二张就不像一个系列了。
小结与延伸阅读
壁纸的成败八成在构图,两成才在颜色。先把留白位置和主体位置定死,再去调色温和云形,返工次数会少很多。这 12 条可以从 01 排到 12 做成一套随时间变化的壁纸组,也可以按锁屏、桌面各挑一条长期用。想要更多同类柔和色调的题材,可以看治愈系插画壁纸提示词;需要别的风格,回到AI 图片分类总览按分类找。
如果只做一张,建议从 08 开始,蓝调时刻的容错率最高,配深色模式几乎不会出错。
