Overall style

Use a mid-20th-century modernist retro editorial illustration style, blending the design language of vintage book covers, vintage magazine covers, film noir and geometric graphic design.

The image should be:

black-dominant; retro and premium; rational and restrained; simple and striking; geometrically simplified; strongly cover-like.

Do not default to a detective theme; choose the most fitting imagery for the topic, while always keeping the same retro modernist visual language.

Color rules

Keep the whole image strictly within 3 colors:

1. Black as the absolute main color, covering most of the background or subject; 2. White or off-white as the secondary color; 3. Only 1 bright accent color.

The accent color can be one of red, green, blue, orange, purple or yellow, chosen to suit the topic.

Do not use several bright colors at once; no highly saturated multicolor; no complex gradients; use the accent color only on part of the subject, key words of the title, geometric shapes or a few emphasis elements.

Composition

Arrange the composition to fit the chosen aspect ratio.

Choose automatically to suit the topic:

image left, text right; text left, image right; central subject with information on both sides; top and bottom sections; a poster layout led by a single subject.

Keep only:

one core subject; one visual center; one main color focus; one set of main title information.

Balance the subject and the text; keep the structure clear and do not overcrowd it.

Subject treatment

Distill the single most representative core image from the topic.

Render the subject with:

geometric outlines; large flat color blocks; silhouette-style light and shadow; simplified features and details; a little exaggerated proportion; retro editorial illustration.

People, products, buildings, robots, service scenes or abstract concepts should all be reduced to clear, simple, easily recognized visual symbols.

No realistic photography; no 3D; no anime style; no complex mechanical detail; no piles of unrelated decoration.

Typography

The main title must stand out as the first visual center of the image.

Set the Chinese main title in a typeface with strength, a book-cover feel or an editorial feel.

The English subtitle can use an elegant serif or a clean uppercase face.

Keep supporting text to a minimum, only what is necessary.

Do not use lots of tags, specs, icons, numbering or captions.

Texture

Add slight vintage paper grain, screen-print, old book-cover or worn-ink texture.

Keep the grain restrained; do not make it shabby, dirty or badly faded.

Keep the whole image crisp, flat and easy on the eye.

Edges

The image must be full bleed.

Content runs straight to all four edges of the canvas.

No white border; no card-style frame; no rounded white edges; no margins around the image; no light-colored outer rim.

Do not

No neon cyberpunk; no modern tech blue-purple gradients; no multicolor palettes; no complex lighting effects; no glass textures; no metallic 3D; no lots of small icons; no information overload; no generic internet promo-poster look.

Final effect

The final image should look like a premium retro feature cover or a classic book cover:

black dominant; a clear black-and-white relationship; only one bright color; a simple, powerful subject; a clear, striking title; restrained and premium, with a mid-century modernist retro editorial character.
