A decision system for quiet, useful, material-led visual design.

The system · Compositions · Workflow · Prompts · Install

Turn a product, object, material, photograph, event, or idea into an original quiet-living visual. The skill uses restrained natural color, functional hierarchy, honest material evidence, and generous asymmetric whitespace without copying MUJI branding or recognizable campaigns.

It is a decision system rather than a beige filter. Each run chooses a composition from the content, assigns one material anchor, resolves every visual choice, and checks the result against a concrete quality gate.

Quiet does not mean empty. It means every object, word, color, and gap has a reason to remain.

The system

System	Direction
Input	A product, object, material, photograph, event, daily action, or concept
Composition	Selected from seven content-led families rather than one fixed minimal template
Palette	Material-derived off-white, warm gray, sand, natural brown, charcoal, and optional muted red
Space	50%–75% empty in image-led work; 35%–55% in information-led work
Image	Natural light, soft shadows, tactile evidence, moderate depth of field, and minimal retouching
Type	Neutral sans serif, clear hierarchy, left alignment, and no decorative filler
Output	Generated raster image, production-ready prompt, and a one-line visual recipe

Composition families

01–04	05–07
Small-object field · one useful object, 55%–75% empty space Quiet information grid · factual content, 2–3 columns Observed-life crop · supplied photography as evidence Material study · fibers, grain, glaze, wear	Editorial pause · one phrase, one small visual cue Useful line drawing · only details that explain the action Domestic still life · one subject, no more than two supports

Workflow

Step	Decision	Result
01	Read the input	Subject, purpose, audience, exact text
02	Choose the layout	One of seven composition families
03	Anchor the material	Paper, wood, cloth, clay, glass, or metal
04	Compose the silence	Numeric subject size, margins, empty space
05	Add one human trace	One sign of handling, use, repair, or action
06	Generate and inspect	Function, hierarchy, evidence, originality

Visual rules

1. Function comes first. Communicate the purpose before the style.
2. Material colors lead. Every visible color belongs to a physical surface, text role, or believable shadow.
3. Silence is measured. Empty space follows a numeric range and controls sequence rather than surrounding a centered object.
4. One material anchors the image. Fibers, grain, glaze, transparency, or wear replace generic texture overlays.
5. One human trace is enough. Use exactly one concrete sign of handling, use, repair, or present action.
6. Every choice is resolved. The final prompt contains one crop, position, light direction, material, and trace.
7. Originality is structural. No MUJI wordmark, red brand block, packaging system, product code, campaign copy, or recognizable composition is reproduced.

Not this

• not a beige filter or a centered object on an empty background every time
• not glossy e-commerce photography or luxury-product lighting
• not a card grid, decorative badge system, gradient, or 3D composition
• not a prop-heavy lifestyle scene or perfect showroom arrangement
• not kawaii illustration, sticker clusters, mascots, or ornamental doodles
• not a reconstruction of MUJI branding, packaging, advertising, or store design

Try it

Objects & materials — product study and tactile evidence

Product study

Use muji-style-skill to create a 3:4 product poster for a daily-used white ceramic mug with slightly uneven glaze. No text. Keep it quiet and natural, without polished e-commerce styling.

Material study

Use muji-style-skill to create a quiet material-study poster about unbleached linen that has been washed many times. Emphasize fibers, folds, and natural light. Add no props.

Information & editorial — exact copy and measured silence

Information poster

Use muji-style-skill to design a vertical poster for a community plant exchange. Preserve this exact copy:

Plant Exchange Day
October 18, 10:00–15:00
Qinghe Community Courtyard

Keep the information clear and do not add decorative illustration.

Editorial poster

Use muji-style-skill to create a 3:4 editorial poster for the exact phrase “use slowly, repair carefully.” Keep the subject small and preserve at least 65% empty space.

Everyday scenes — ordinary life without lifestyle staging

Domestic still life

Use muji-style-skill to compose an early-morning kitchen still life with a wooden tray, a white ceramic bowl, and one pear. Make it feel inhabited, but include exactly one concrete sign of use.

Landscape photograph

Use muji-style-skill to create a 16:9 image of white cotton socks drying in natural light. Emphasize the cotton texture and ordinary domestic life. No title and no commercial-advertising finish.

Drawing & originality — useful lines and an unbranded result

Line illustration

Use muji-style-skill to draw an informational line illustration of hands repairing an old wooden chair. Show only the details needed to understand the action. No cute characters, stickers, or decorative doodles.

Originality stress test

Create an original, unbranded quiet-living poster for a compact aroma diffuser. Preserve functional clarity and material honesty, but do not reproduce any MUJI logo, red block, product code, price label, packaging, campaign copy, or known advertisement composition.

Delivery format

Image	Prompt	Recipe
Generated raster image when available	Exact production-ready generation prompt	One line naming palette, composition, material, and treatment

If image generation is unavailable, the skill returns the prompt and states that limitation.
