Text for your agent

Install the skill: git clone https://github.com/yanliudesign/mono-color-skill.git ~/.claude/skills/mono-color, then restart Claude Code. In other agents load SKILL.md as the entry point.

Other ways from the author
git clone https://github.com/yanliudesign/mono-color-skill.git ~/.claude/skills/mono-color

Restart Claude Code after installing.

What it does

The skill turns a theme, phrase or photo into an editorial poster with one stable visual system: a neutral paper substrate, one or two printing inks, halftone photography, active negative space and expressive type. It first resolves a recipe manifest, then outputs the final generation prompt and the raster image itself with a short note on palette, layout and print process. The design system lives in separate files: palettes, rhythm, typography, compositions. There are examples and swatch samples.

Who it is for. For designers and authors who need a poster or cover in a coherent one-ink editorial style.

Good fit when

  • You need a poster or cover in a one-ink print style
  • You need a halftone take on a photo with negative space and type
  • You need a ready prompt and image for a theme or article

Not a fit when

  • You need full-color photorealistic graphics
  • The agent cannot generate images and you need more than the prompt

Example request

Make a one-ink editorial poster about a night market, blue ink on paper

Limitations

Producing an image needs an agent with image generation, otherwise the skill returns only the prompt and recipe. The style is deliberately limited to one or two inks on a paper substrate and does not fit other aesthetics.

How to disable. Remove the mono-color folder from the agent's skills directory.

Security check

  • The skill consists of instructions, a design system and prompts
  • Image generation and helper scripts run on your side

README in short

The README describes mono-color as an editorial print skill with an adaptive paper substrate, one or two inks, halftone and restrained type without defaulting to pure retro. Install clones the repo into the Claude Code skills directory, and other agents read SKILL.md as the entry point. The repo holds the design system split into files, swatch sets, examples and scripts to build the style board and validate it. MIT licensed, with a separate license for the assets.

SKILL.md

name: mono-color
description: Generate original one-ink or controlled two-ink editorial images from any theme, sentence, article idea, object, or reference photo. Always use this skill when the user asks for 单色海报、双色印刷、单色调视觉、蓝色/绿色孔版印刷、risograph、网点照片、复古或当代编辑排版、zine poster, monochrome editorial poster, duotone print, or asks to use the mono-color style. It uses an adaptive white, gray, or pale-beige substrate, no more than two printing inks, active negative space, terse human language, and strong serif/grotesk/mono typography without making retro styling the default or copying a source composition, wording, logo, or artwork. Produce both the final generation prompt and the generated raster image unless the user explicitly asks for prompt only.

# Monocolor Editorial Print

Turn any user theme or image into an original printed editorial artifact with one stable visual language:

> adaptive neutral substrate + one or two inks + reproduced image + typographic tension + concise human voice

Do not imitate any one reference. Recombine the system below into a new composition every time.

## Default Deliverable

Create:

1. one final image-generation prompt;
2. one generated raster image;
3. a short recipe note naming palette, layout family, type pairing, and print process.

Save generated files under `~/Desktop/Claude skills/mono-color/` when a file path is available. Create the folder if needed. Stop at prompt-only only when the user explicitly asks for it or no image-generation capability is available.

## Input Reading

Extract four things before composing:

- **Subject:** the one person, object, scene, or idea that must remain recognizable.
- **Intent:** poetic observation, announcement, field note, personal statement, cultural poster, or specimen page.
- **Words:** preserve exact supplied text in its original language. When no text is supplied, invent one English display phrase of 2-8 words and preserve it across retries. Omit display text only when the user explicitly requests a text-free image.
- **Image role:** hero photograph, isolated specimen, cropped fragment, texture source, or no supplied image.
- **Representation:** faithful reproduction or abstract symbol extraction. Choose abstract symbol extraction when the user asks for abstract, artistic, loose, experimental, less realistic, or less photographic treatment.

For a complex topic, choose one concrete visual metaphor. Do not illustrate every point.

FAQ

What does the skill output?
