🚀 Installation

Prerequisites

• MkDocs >= 1.4.X
• Python >= 3.10

Install the plugin from PyPI using pip:

pip install mkdocs-color-swatch-plugin

Then enable it in your mkdocs.yml:

plugins:
  - color-swatch

Make sure you have mkdocs installed:

pip install mkdocs

✍️ Syntax & Usage

To add swatches to your Markdown, use the simple, custom inline format:

:color[#e74c3c]: -> Red
:color[rgb(52, 152, 219)]: -> Green
:color[rgba(46, 204, 113, 0.6)]: -> Blue

Each tag will render as:

• A visual color preview
• Dynamically generated tooltips showing the color value and label
• A smooth hover animation for swatch elements

🧠 Why Use This Plugin?

Instead of manually writing HTML for every color sample like:

<span style="background-color: #e74c3c; width: 30px; height: 30px; ..."></span>

You can just write:

:color[#e74c3c]:  

It's faster, cleaner, and scales dynamically with your content.

• 🎯 Simple syntax for embedding colors directly in your Markdown files
