Site Palette for Chrome: Generate, Edit, and Share Color Palettes FastColor is one of the most powerful elements in design — it shapes brand identity, guides user attention, and sets emotional tone. Site Palette for Chrome is a lightweight, focused extension that helps designers, developers, and content creators quickly extract, generate, edit, and share color palettes directly from any webpage. This article explains what Site Palette does, why it’s useful, how to use it effectively, advanced features and workflow tips, and alternatives to consider.
What is Site Palette for Chrome?
Site Palette for Chrome is a browser extension that extracts and builds color palettes from webpages. When activated, the extension analyzes a site’s visible content and returns a curated set of colors that represent the page’s visual style. Beyond extraction, it provides tools to refine palettes, convert colors between formats, and export/share palettes for use in design apps or development projects.
Why use Site Palette?
- Rapid palette creation: Instead of manually sampling multiple elements, Site Palette gives you a ready-made palette in seconds.
- Consistency and inspiration: Extracting colors from existing sites helps replicate a brand’s mood or discover fresh combinations.
- Developer-friendly outputs: Palette exports often include CSS variables, hex/RGB values, and downloadable assets, making integration straightforward.
- Collaboration and sharing: You can export palettes or share them with teammates as images, code snippets, or linked collections.
Key features
- Color extraction: Samples dominant and accent colors from a page’s visible area.
- Editable swatches: Tweak hue, saturation, and lightness to perfect contrasts or brand compliance.
- Format conversion: Display and copy values as HEX, RGB(A), HSL, and CSS variables.
- Export options: Export as images, JSON, CSS, or copy ready-to-use code snippets.
- Simple sharing: Generate shareable links or export files to pass to teammates or import into design tools.
- Lightweight and fast: Minimal performance overhead, designed for quick on-the-fly use.
How Site Palette works (step-by-step)
- Install the extension from the Chrome Web Store and pin it to your toolbar for quick access.
- Navigate to any website or webpage you want to sample.
- Click the Site Palette icon. The extension quickly analyzes the visible content and displays a palette of colors it detects — typically including primary, secondary, background, and accent tones.
- Click a swatch to reveal editing controls (brightness, saturation, hue) and alternative formats (HEX, HSL, RGB).
- Adjust colors as needed to meet accessibility or branding requirements.
- Export your palette in the desired format (CSS variables, JSON, image, etc.) or copy values to the clipboard for immediate use.
Practical workflow examples
- Rapid brand audits: Load a client’s homepage and extract their color system to document brand assets for a design brief.
- UI mockups: Pull a palette from a competitor site to quickly prototype a UI with similar visual language.
- Accessibility checks: Adjust extracted colors to reach WCAG contrast ratios and export updated values as CSS variables for development handoff.
- Inspiration boards: Collect palettes from multiple sites and export a combined JSON or image for mood boards.
Editing and refinement tips
- Balance dominant vs. accent colors: If the page you sample is image-heavy, Site Palette might pick many image colors. Choose a small set of core UI colors and separate decorative tones.
- Test contrast early: Use the extension’s brightness and contrast adjustments to ensure text remains legible on backgrounds.
- Harmonize with HSL: Small HSL adjustments often produce better-coordinated palettes than large hex swaps.
- Lock specific brand colors: If you must preserve a brand’s primary color, lock that swatch and let the extension generate complementary tones around it.
Exporting and integrating palettes
Site Palette typically supports several export routes:
- CSS variables: Useful for direct integration into a website’s stylesheet.
- JSON: Importable into design systems, plugin workflows, or storage for later use.
- Image (PNG/SVG): Handy for sharing on Slack, in documents, or adding to mood boards.
- Copy-to-clipboard: Single-click copy of hex/RGB/HSL values or ready-made CSS snippets.
Example CSS variable output (you’ll copy from the extension into your code):
:root { --site-primary: #1a73e8; --site-secondary: #ffb74d; --site-bg: #ffffff; --site-accent: #e91e63; } Accessibility and contrast
Color extraction is only the first step. Always validate contrast for text, interactive elements, and states (hover, disabled). Use the extension’s editing tools to raise luminance or adjust saturation and re-test until you pass WCAG AA or AAA where required. For body text, aim for a contrast ratio of at least 4.5:1 (small text) or 3:1 (large text).
Limitations and when to be cautious
- Visible-area sampling: Site Palette analyzes visible pixels; it may miss colors used in other states or under different responsive layouts.
- Image bias: Photographic content can dominate extracted palettes. When designing UI, prioritize UI element colors over image-derived tones.
- Not a full design system generator: It’s a rapid prototyping and extraction tool, not a replacement for a carefully documented design system.
- Browser-only: Works inside Chrome (or Chromium-based browsers) as an extension; it’s not a standalone web app unless provided by the developer.
Alternatives and complements
- ColorZilla: Advanced eyedropper and gradient tools for Chrome.
- Coolors: Rapid palette generation and sharing, web and app versions.
- Adobe Color: Powerful color theory tools and accessibility checks.
- Figma plugins (e.g., Palette, Color Extractor): For in-app extraction and direct import into design files.
Comparison table
| Tool | Best for | Export options |
|---|---|---|
| Site Palette | Quick extraction from live pages | CSS variables, JSON, images, HEX/RGB |
| ColorZilla | Precise sampling and gradients | HEX, clipboard |
| Coolors | Generating and iterating palettes | PNG, SVG, URL, JSON |
| Adobe Color | Color theory and accessibility | ASE, PDF, copy values |
| Figma plugins | Direct import into design files | Direct into Figma document |
Pro tips
- Combine Site Palette with a Figma plugin: Extract in Chrome, then import into Figma for component-level testing.
- Save frequently used palettes as JSON for consistent reuse across projects.
- Use CSS variables exports to quickly switch themes or build dark/light mode toggles.
- When sampling brand sites, check multiple pages (homepage, product pages, dashboard) to capture the full color language.
Conclusion
Site Palette for Chrome is a fast, practical tool for extracting, editing, and sharing color palettes directly from live websites. It accelerates brand audits, prototyping, and developer handoffs by producing ready-to-use values and export formats. Used alongside accessibility checks and design-system practices, it becomes a powerful step in a designer’s workflow — turning visual inspiration from any webpage into implementable color systems in minutes.
