Automated summary

Extracts dominant colors from an image and generates a color palette.

Strengths

Easy to use with a single command
Supports multiple output formats (hex, rgb, tuple, JSON)
Allows choosing the number of colors and extraction quality

Limitations

Requires the image to be accessible locally
Extraction quality depends on image complexity
Does not handle remote images

When to use it

When you need to quickly extract a color palette from an image for a design or development project.

When not to use it

If you require advanced color analysis with segmentation or pattern recognition algorithms.

Security analysis

Safe

Quality score90/100

The skill runs a local Python script to extract color information from an image file. It does not involve network access, external commands, or destructive operations. The allowed tools are limited to Bash (python) and Read, which are used in a safe manner.

How this analysis is made

Examples

Extract dominant color from logo

What are the main colors in this logo? /path/to/logo.png

Generate a 6-color palette as hex

Extract 6 dominant colors from this image and show them as hex values: /path/to/photo.jpg

JSON output for programmatic use

Get the dominant colors from this image in JSON format: /path/to/image.png

Dominant Color Extraction

Name: Dominant Color Extraction
Author: Skills Guide Bot

Extract dominant colors from an image file using the extract_colors.py script.

Script Usage

python ~/.claude/skills/dominant-color/scripts/extract_colors.py <image> [options]

Options

| Flag | Description | |------|-------------| | -n, --count N | Number of colors to extract (default: 5) | | -q, --quality 1-10 | Extraction quality, 1=best (default: 1) | | -f, --format FORMAT | Output format: hex, rgb, tuple, full | | --json | Output as JSON | | --dominant-only | Only output the dominant color |

Examples

# Basic usage
python script.py image.png

# Get 8 colors as hex values
python script.py image.jpg -n 8 -f hex

# JSON output for programmatic use
python script.py image.png --json

# Just the dominant color
python script.py image.png --dominant-only -f hex

Instructions

Run the script with the image path provided by the user: $ARGUMENTS
Present the extracted colors clearly
If the user needs the colors for code, offer to format them as CSS variables, Tailwind config, or other formats

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/dominant-color-extraction-mm8o51mj/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/dominant-color-extraction-mm8o51mj' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/dominant-color-extraction-mm8o51mj/download' --output '.skill-downloads/dominant-color-extraction-mm8o51mj/SKILL.md.part' && mv '.skill-downloads/dominant-color-extraction-mm8o51mj/SKILL.md.part' '.skill-downloads/dominant-color-extraction-mm8o51mj/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

Tools declared by the author (check availability in your agent): Bash(python *), Read

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/dominant-color-extraction-mm8o51mj/SKILL.md' && test -s '.skill-downloads/dominant-color-extraction-mm8o51mj/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/dominant-color' && cp -R '.skill-downloads/dominant-color-extraction-mm8o51mj' '.claude/skills/dominant-color'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation

openskills install './.skill-downloads/dominant-color-extraction-mm8o51mj'

openskills read 'dominant-color-extraction-mm8o51mj'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/dominant-color-extraction-mm8o51mj/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
