提示词库 · 像素画
十个实测的复古游戏美术提示词——16位小镇广场、地牢内景、道具图标表、视差天空。每张卡片都展示未经修改的输出、模型和价格，以及事后需要手工修的地方。
像素画有一个别的题材都不需要的提示词成分：年代。「16-bit SNES-era pixel art」和「8-bit NES-era pixel art with a four-colour palette」产出的图完全不同，因为年代本身就带着分辨率、色彩数量和明暗处理的惯例。再加上调色板规模——「limited 32-colour palette」——以及明暗风格——「dithered shading」「flat cel shading with a single highlight」——三个真正要紧的设定就齐了。然后像平常一样描述场景：「a small harbour town square at dusk, cobblestones, market awnings, a fountain, warm lamplight in the windows」。
对这些模型能做什么、不能做什么要诚实。Nano Banana渲染的是很有说服力的像素风*插画*——观感、配色、氛围——但它并不对齐到真正的像素网格，所以放大之后会看到方块并不完全均匀，边缘还有零星抗锯齿像素。用于情绪板、主视觉、商店banner和风格摸索，这些完全看不出来，也完全可用。要做进引擎的精灵图，就把输出当参考，在Aseprite里重绘或降采样。下面十张图都是在BananaBanana上生成的首次未修改输出，大多用的是$0.03的Lite。
「8-bit NES-era」给你厚实的方块、硬朗的黑色描边和寥寥几种颜色——很适合图标、UI，以及任何必须在极小尺寸下可读的东西。「16-bit SNES-era」是多数人说「像素画」时真正想要的那个甜点区：颜色够用来做渐变和抖动，却依然明确是像素，而且能撑起有纵深的场景。「Modern indie pixel art with soft lighting and subtle gradients」走得更远，更接近今天商店页面上的美术风格。
无论选哪个，都要在整套里保持一致，连同调色板那句一起。用同样的年代和调色板措辞生成的小镇、地牢和森林会像同一款游戏；用三个不同的年代词生成，它们看起来就像三款不同的游戏。让图标套装成立的那套纪律，同样让tileset成立。
下面每张图片都是所在卡片提示词的未修输出——没有从几十次尝试里挑好的，也没有修图。模型徽标标明了它由什么生成、花了多少钱。
16-bit SNES-era pixel art scene of a small harbour town square at dusk: cobblestone paving, striped market awnings, a stone fountain in the centre, fishing boats moored beyond the sea wall, warm lamplight in the windows. Limited 48-colour palette of dusk violet, teal and warm amber, dithered sky gradient, crisp chunky pixels, side-scrolling game perspective.
16-bit SNES-era pixel art of a stone dungeon chamber seen from a top-down three-quarter angle: cracked flagstones, two lit wall torches throwing orange pools of light, a wooden treasure chest, iron bars in the archway and a puddle reflecting the flame. Limited 40-colour palette of cold grey-blue and torch orange, dithered shading, hard black outlines, classic RPG look.
16-bit pixel art side-scrolling forest background with three depth layers: dark foreground ferns, mid-ground pine trunks, and pale misty hills far behind. Shafts of morning light between the trees, floating pollen specks. Limited 32-colour palette of deep green, sage and cream, dithered atmospheric fade between layers, no characters, seamless-feeling composition.
8-bit NES-era pixel art sprite sheet on a plain dark slate background: a neat grid of nine RPG item icons — a red potion flask, a bronze key, a leather pouch, a short sword, a round shield, a scroll, an apple, a lantern and a silver ring. Chunky uniform pixels, hard black outlines, flat four-tone shading per item, limited 16-colour palette, even spacing between icons.
16-bit pixel art interior of a small wooden cabin: a lit fireplace with a kettle on a hook, a rug, a bookshelf, a round table with a bowl and a candle, and snow visible through the window. Warm amber firelight against cool blue window light, limited 40-colour palette, dithered shading, front-facing room view like a classic adventure game.
16-bit pixel art side-scrolling scene of sandstone ruins in a desert: broken columns, a half-buried archway carved with spirals, scrubby bushes and a distant plateau under a hot flat sky. Limited 32-colour palette of ochre, rust and pale sky blue, dithered heat haze on the horizon, crisp pixel edges, no characters.
16-bit pixel art interior of a small spaceship bridge seen from behind the pilot seat: a curved control console with rows of blinking indicator lights, a wide viewport showing a starfield and one ringed planet, cables running along the ceiling. Limited 40-colour palette of steel blue, cyan glow and deep space black, dithered light falloff, retro sci-fi game look, no readable text on screens.
16-bit pixel art of a night street food stall: a wooden cart under a warm hanging bulb, steam curling from a pot, skewers on a small grill, stacked bowls and a stool beside it, wet asphalt reflecting the light. Limited 40-colour palette of night blue and warm orange, dithered glow around the bulb, cozy and detailed, no text on the banner.
16-bit pixel art character sprite sheet on a plain light grey background: one adventurer in a green hooded cloak with a satchel, shown in four poses in a single row — standing, walking, raising a lantern, and sitting. Consistent proportions and palette across all four, limited 24-colour palette, hard outlines, flat three-tone shading, classic RPG overworld scale.
16-bit pixel art landscape of a small stone shrine on a mountain ledge at sunrise: a stepped path winding up to it, two lanterns on posts, pine trees clinging to the rock, and layered peaks fading into pink and gold sky. Limited 48-colour palette, heavy dithering in the sky gradient, silhouetted foreground rocks, wide serene composition.
「8-bit NES-era」和「16-bit SNES-era」自带分辨率、色彩数量和明暗惯例。不写它，正是像素类提示词回来时像给普通插画加了层模糊滤镜的主要原因。
「Limited 32-colour palette of deep green, sage and cream」正是让像素画有整体感的东西。不设上限，提示词会还你几百种色阶，复古味也就蒸发了。
天空和光线衰减里的抖动渐变是那个年代的签名。写上「dithered sky gradient」你就能拿到；含糊带过，得到的是平滑的现代渐变，幻觉当场破功。
网格在数学上并不干净，所以能进游戏的精灵图仍需在Aseprite里过一遍。而主视觉、banner、情绪板和商店页面，直接用原始输出就够了。
不是。这些模型渲染的是像素画的外观，而不是严格对齐到网格，所以放大到400%你会看到不规则的方块和边缘几个抗锯齿像素。在正常观看尺寸下毫无破绽，这正是它适合banner、情绪板和概念阶段的原因——也是可进引擎的精灵图仍需手工清理一遍的原因。
按1K生成，在编辑器里狠狠降采样——用最近邻缩到64×64或128×128，不要平滑——然后手工清理边缘。你保留了模型找到的构图和配色，最后得到一张诚实的网格图。
在一张图里要求多个姿势，就像上面那张主角精灵表——一次生成意味着对服装和配色只有一种解释，比分四次跑稳定得多。仔细看我们这张，人物并不都在同一比例上：这就是诚实的边界。先在一个姿势上把角色定下来，再编辑这张图去做其他姿势，而不是重新提示。
$0.03的Lite在这里真的很能打，因为扁平、有限配色的美术是小模型最容易做对的东西——上面一半提示词用的都是它。遇到有层次纵深、辉光和反射的场景再升到Nano Banana 2，比如港口、地牢和神社。
可以——你在BananaBanana上生成的图片归你所有。发行平台越来越多地要求在上架时声明AI生成的素材，所以请查一下你要发布的那个平台的规则。
