Theme Factory

Theme Factory is Anthropic's official Claude Agent Skill for styling artifacts with consistent, professional themes. It ships 10 pre-set themes, each with a curated color palette (hex codes) and complementary header/body font pairings, and it can generate a brand-new theme on the fly when none of the presets fit. Apply any theme to slide decks, documents, reports, HTML landing pages, or any other artifact Claude creates.

What is Theme Factory?

Theme Factory is a packaged toolkit of design themes for Claude. Each theme is a self-contained specification in the skill's themes/ directory, defining a cohesive color palette with hex codes and a matching font pairing for headers and body text. A bundled theme-showcase.pdf previews all 10 themes visually so you can pick one by eye. The skill is published by Anthropic in the official anthropics/skills repository and is loaded by Claude as an Agent Skill.

What it does

• Provides 10 ready-made themes: Ocean Depths, Sunset Boulevard, Forest Canopy, Modern Minimalist, Golden Hour, Arctic Frost, Desert Rose, Tech Innovation, Botanical Garden, and Midnight Galaxy.
• Shows a visual theme showcase PDF so you choose a look before applying it.
• Applies the selected palette and fonts consistently across every slide or section of an artifact.
• Generates a custom theme when the presets do not match, naming it to describe its color/font character and showing it for review before applying.
• Maintains proper contrast and readability while preserving each theme's visual identity.

How it works

When you ask Claude to style an artifact, the skill first displays theme-showcase.pdf so you can see all available options. You pick a theme, Claude reads the corresponding file from the themes/ directory, and it applies the specified colors and fonts throughout the deck or document. If no preset works, Claude generates a new theme from your description, shows it for verification, then applies it the same way. The whole flow is conversational: show options, confirm a choice, apply consistently.

Who it's for

This skill is for anyone using Claude to produce visual artifacts who wants a polished, on-brand look without hand-picking colors and fonts. It suits consultants building slide decks, teams shipping reports and docs, and developers generating HTML landing pages. Designers and non-designers alike get a fast path to cohesive styling.

What you can build

• Themed slide decks for pitches, reviews, and internal updates.
• Styled documents and reports with consistent typography and color.
• Branded HTML landing pages and web artifacts.
• A custom theme tailored to a specific brand or mood, generated on demand.

Why it matters

Consistent color and typography are what separate a professional artifact from a generic one, but choosing a cohesive palette and font pairing is slow and easy to get wrong. Theme Factory encodes that design judgment into 10 vetted themes plus an on-the-fly generator, so Claude can style anything it creates in seconds while keeping contrast, readability, and a clear visual identity intact. Because it is an official Anthropic skill, it integrates cleanly with Claude across Claude.ai, Claude Code, and the API.

1. Install in Claude Code

Add the Anthropic skills marketplace, then install the example skills plugin:

/plugin marketplace add anthropics/skills
/plugin install example-skills@anthropic-agent-skills

Or add just this skill with the skills CLI:

npx skills add anthropics/skills --skill theme-factory

2. Use it

Ask Claude to style an artifact, for example: "Apply a theme to this slide deck." Claude shows the theme showcase, you pick one (or ask for a custom theme), and Claude applies the colors and fonts throughout.
