Extract the brand colors from https://example.com using CSS variables.
Your agent does
I have generated assets/palette_lite.py. This script will fetch the site and extract variables like --primary and --brand-color. Run it to get the hex codes.
What you get
About this skill
The problem
Manually digging through DevTools to find a brand's specific hex codes is tedious. Design workflows often stall when you need to match a site's primary palette but colors are hidden behind CSS variables.
What it does
- Scrapes public URLs to identify CSS custom properties.
- Filters for specific naming conventions like --primary, --accent, and --brand.
- Generates a standalone Python script to automate color extraction.
- Operates using only standard libraries with no external dependencies required.
Frameworks & tools
Python, CSS Custom Properties (Variables).
Why this beats prompting it yourself
Generic prompts often fail to target the specific naming conventions used in modern design systems. This skill provides a focused extraction logic that ignores utility noise and targets meaningful brand tokens out of the box.
Use cases
- Quickly extracting brand colors for a client proposal.
- Scaffolding a theme for a new site based on an existing design system.
- Auditing CSS variables across a landing page for brand consistency.
Known limitations
Cannot extract colors set via JavaScript or hidden in external shadow DOMs. Limited to CSS variables only, it does not analyze images or computed styles.
