What is orange-line-illustration?

Orange Line Illustration is a visual style kit packaged as a skill for AI agents. It produces drawings in a New Yorker-style editorial look: thin black ink lines on a plain white background, large areas of empty space, and a single warm orange accent color placed on the most meaningful part of the image. The philosophy behind it is captured in the project's own tagline: one idea, one accent, lots of silence. The kit was built by the author while illustrating a set of product-building principles, so it comes from actual use rather than theory. It ships as a directory you drop into your AI agent's skills folder, which makes it compatible with tools like Cola, Claude Code, and Codex, any tool that supports the SKILL.md convention. Once installed, you can ask your agent in plain language to create illustrations in this style and it follows the rules automatically. Inside the kit you get a style specification covering line weight, background treatment, the single orange color value, how to draw people very small against large objects, and the overall mood to aim for. There is also a section on a design method the author calls metaphor design, which focuses on finding scenes with visual tension rather than abstract symbols, with documented examples of what worked and what did not. Prompt templates are included so the rules translate directly to any image-generation model that accepts text instructions. The project uses a dual license. Open-source projects and personal use are free. If you are using it inside a closed-source or commercial product, you need to buy a commercial license.
