Description

Color palette extractor — extract dominant colors from an image (PNG/JPEG/GIF). Use when you need a color palette for design or analysis. Pure stdlib, no LLM.

README (SKILL.md)

axiom-color-palette

Version: 0.1.2 Axioma Tools

Extracts the dominant color palette from an image using frequency analysis.

What this skill does

Frequency-based color extraction
Configurable palette size (3-16 colors)
Optional K-means clustering
Outputs hex codes + RGB tuples
JSON output for design tools

When to use this skill

✅ Generate palette for website redesign
✅ Find dominant brand colors in an image
✅ Analyze color trends in design portfolios
❌ Convert color spaces (use colormath)
❌ Render images (use Pillow)

Usage

python3 axiom_color_palette.py logo.png --colors 5
python3 axiom_color_palette.py photo.jpg --json > palette.json

from axiom_color_palette import extract_palette
colors = extract_palette('image.png', n_colors=5)
# [('#FF5733', 42), ('#33FF57', 28), ...]

Validation

Usage Guidance

Review before installing. This skill looks locally contained and non-destructive, but do not rely on it for image-based palette extraction; install it only if you want a simple hex-color harmony generator, or wait for the publisher to align the metadata, docs, and implementation.

Capability Assessment

⚠ Purpose & Capability

The published SKILL metadata and multilingual skill docs claim PNG/JPEG/GIF dominant-color extraction, but README.md and axiom_color_palette.py describe and implement palette generation from a base hex color.

⚠ Instruction Scope

Usage instructions conflict: SKILL.md shows image-file commands and an extract_palette API that do not exist, while the CLI actually accepts a hex color and harmony options.

✓ Install Mechanism

No installer, dependency installation, shell persistence, or package-management behavior is present in the artifact set.

ℹ Credentials

Runtime behavior is narrow and local: it uses Python stdlib color math, parses user-supplied color strings, and prints palette data. It does not read images despite the advertised purpose.

✓ Persistence & Privilege

No background execution, credential access, network calls, broad filesystem access, privilege escalation, or persistent state changes were found.

How to Use

Make sure OpenClaw is installed (local or Docker)
