Monocolor Editorial Print
A one-ink and controlled two-ink editorial image skill for posters, zines, portraits, packaging, and visual field notes.
Turn a theme, sentence, object, or supplied photograph into an original editorial image. The skill defaults to controlled two-ink with one dominant plate and one narrowly assigned accent plate. Explicit one-ink or monochrome requests remain pure one-ink. White, cool gray, or pale-beige substrates are selected from the image and palette; contemporary editorial is the default, while vintage treatment appears only when requested.
It preserves a visual system rather than copying a reference. Every composition is rebuilt around the subject, intent, words, and image role.

What it does
System
Direction
Input
A theme, phrase, object, article idea, or supplied photograph
Palette
Adaptive neutral white, cool gray, or pale beige + controlled two-ink by default; explicit one-ink requests stay one-ink
Modes
Pure one-ink, chromatic + black, complementary duotone, or overprint duotone
Image
Halftone, risograph grain, cyanotype exposure, or photocopy breakup
Space
25%–55% visible empty paper on an asymmetric editorial grid
Type
Content-responsive literary serif, cultural grotesk, condensed civic, programmatic, rotated, handwritten, or word-as-object roles
Output
Generated raster image, exact production prompt, and a short recipe
Use cases
Posters: events, parties, art exhibitions, city walks, and conceptual posters
Social media: Xiaohongshu covers, WeChat article headers, podcast covers, and cultural commentary illustrations
Brand materials: postcards, invitations, tickets, programs, menus, and packaging stickers
Keepsakes: travel journals, photo album covers, and anniversary cards
Books and publications: covers, title pages, chapter openers, and zine interiors
Words: literary excerpts, poetry, and personal declarations
All of these formats can use a single ink to reduce production costs while retaining a distinctive visual identity.
How it works
1 Read the input → identify subject, intent, words, and image role
2 Choose the layout → image, specimen, declaration, object field, overprint, journal, or cover
3 Assign the plates → default to two assigned roles; switch to one plate when explicitly requested
4 Compose the page → preserve 25%–55% silence and add one deliberate disruption
5 Generate and inspect → check ink count, identity, hierarchy, texture, and originality
Ink system
One-ink palette: Cobalt, Royal Blue, Botanical Green, Mint Green, Terracotta Orange, Signal Red, Aubergine, and Charcoal.

In two-ink work, the dominant plate normally carries 70%–85% of the printed area. The accent plate carries 15%–30% and must have a specific job such as dates, annotations, selected objects, or overprint intersections. The substrate is not a third color, and the darker color created where two plates overlap is not a third ink.
Substrate is adaptive, not nostalgic by default: Neutral White #FAFAF7 supports crisp cultural, social, event, and image-led work; Cool Gray #E9E9E5 supports architecture, technology, charcoal-led systems, and restrained branding; Pale Beige #F5F1E8 supports tactile, travel, food, intimate, archival, or explicitly nostalgic subjects. Limited inks and halftone do not automatically imply vintage styling.
Visual rules
No more than two printing inks. Controlled two-ink is the default: 70%–85% dominant plate and 15%–30% accent plate, each with a distinct role. Explicit one-ink requests use one plate.
Paper stays visible. The result is a printed page, not a digitally tinted monochrome wash.
Mechanical reproduction leads. Photographs become dots, grain, clipped highlights, ink pooling, and mild registration drift between plates.
Silence has structure. Empty paper occupies 25%–55% of the canvas and controls pacing.
Type has tension and range. Choose one content-responsive display skeleton and one utility voice; use handwriting only as a short optional interjection. A series may change display categories instead of repeating one house treatment.
Identity stays intact. Supplied people, objects, and scenes remain recognizable.
References are grammar, not templates. At least four structural variables change from every supplied reference.
Not this
not a full-color photograph with a monochrome filter
not arbitrary two-color decoration or more than two printing plates
not a glossy mockup, 3D render, gradient poster, or cinematic scene
not a centered template, card grid, sticker collage, or decorative blob system
not dense scrapbook grunge or torn-paper styling
not automatically retro, yellowed, sepia, distressed, or nostalgic because the work uses halftone or limited inks
not marketing copy, invented branding, fake sponsors, URLs, or QR codes
not a reconstruction of a reference poster or artist signature
Install
Clone the repository into your Claude Code skills directory:
git clone https://github.com/yanliudesign/mono-color-skill.git \
~/.claude/skills/mono-color
Restart Claude Code after installation. Other agent environments can load SKILL.md as the skill entry point.
Try it
Use mono-color to make a vertical poster about a midnight convenience store.
The exact headline is “still open”.

Delivery format
One run returns:
a generated raster image when image-generation tools are available;
the exact production-ready prompt used for generation;
a recipe naming the print mode, exact ink palette, layout family, type pairing, print process, and originality changes.
If image generation is unavailable, the skill returns the production-ready prompt and states the limitation.
Stability and validation
Before prompt compilation, the skill resolves every request into a fixed recipe manifest. Unspecified requests use a 3:4 ratio, Neutral White substrate, contemporary editorial direction, 35% empty substrate, and deterministic palette and layout rules. The substrate may switch to Cool Gray or Pale Beige when the image and ink contrast call for it. Supplied photos default to faithful reproduction; requests for abstract, artistic, loose, experimental, or less realistic treatment switch to deterministic symbol extraction that preserves 2-4 identity anchors. Explicit user choices still take precedence within the two-ink and originality limits.
The design-system/ catalogs make the visual grammar reusable and inspectable. They separate color tokens, typography roles, composition geometry, carrier-specific signals, visual rhythm, and controlled print imperfections from the prose workflow. Catalog IDs are the shared contract between reference boards, recipes, and validation.
design-system/rhythm.json defines relaxation as uneven energy rather than uniformly reduced intensity. Each page selects one audacious focal event—oversized type, an extreme crop, one giant detail, a concentrated overprint, or an abnormal scale relationship—then releases the rest through paper, pale screening, and sparse functional type. Without a supplied photograph, people become 2-4 identifying anchors and partial crops instead of complete stock figures or a safe headline-left/photo-right split. Empty paper and unresolved edges now respond to the focal event instead of fixed quotas.
Controlled chance stays in the reproduction layer: contemporary work selects 0-2 restrained effects, while tactile, vintage, or archival-aging work selects 2-3 bounded effects such as uneven ink density, dry-edge breakup, halftone drift, registration drift, or one broken gesture. The stable recipe seed preserves the same marks across retries without moving the composition or reducing text readability.
The four focused reference-analysis boards document the typography, color, layout, and style evidence behind the system:
Typography
Color
Layout
Style
Regenerate the catalog-driven complete board after editing a catalog:
python3 scripts/build_design_system_board.py
The evaluation contract covers defaults, supplied portraits, botanical work, overprint, event information, long-form text, prompt-only output, conflicting color requests, repeated objects, and reference-copying requests. Run it locally with:
python3 scripts/validate_evals.py
python3 scripts/validate_design_system.py
GitHub Actions runs the same contract on every pull request and push to main .

Originality
This skill extracts system-level qualities such as palette, print process, spacing, hierarchy, and communication tone. It does not copy a reference's composition, wording, labels, logos, border system, or distinctive arrangement.
When a user supplies a photograph, the subject is preserved as content while the crop, screening, grid, type placement, and metadata treatment are newly constructed.
