- +Nearest Tailwind color matching for quick utility class lookup
- +Part of an 11-tool suite — CSS, fonts, screenshots, and more

Verdict: Frontend Hero delivers the most complete color workflow: pick any color, get it in any format including Tailwind, and extract every color on the page in one view. No other single extension matches this breadth.
#2Eye DropperBest Free Picker
Popular free color picker extension with an eyedropper tool, color history, and multiple format output.
Strengths
- +Completely free with no limitations
- +Clean eyedropper UI with magnifying glass

- -Occasional sub-pixel accuracy issues on high-DPI displays
- -No CSS or font inspection features
Verdict: Eye Dropper is the best free color picker available. It handles basic color picking well with a clean interface and color history. Developers needing Tailwind output or full palette extraction will need to look elsewhere.
#3Colorzilla Pro
The premium version of ColorZilla with enhanced gradient analysis, advanced color formats, and additional picker modes.
Strengths
- +Enhanced gradient CSS analysis and extraction
- +Multiple picker modes including area average
- +Built-in gradient CSS generator
- +Long track record of stability and compatibility
Weaknesses
- -No Tailwind color output at all
- -Interface feels dated compared to modern alternatives
- -Gradient features are useful but niche
- -Paid upgrade over free ColorZilla with marginal improvements
Verdict: Colorzilla Pro improves on the free version with gradient analysis and advanced modes. However, it still lacks Tailwind support and modern UI conventions that newer tools provide.
#4ColorZilla
The original and most installed color picker extension with an eyedropper tool, color history, and basic CSS gradient generator.
Strengths
- +Free to use with no feature restrictions
- +Includes a basic CSS gradient generator
- +Millions of installs — well-tested and compatible
- +Supports HEX, RGB, and HSL output
Weaknesses
- -Dated interface that has not been modernized
- -No Tailwind color output or nearest match
- -Clipboard issues reported by some users
- -No full page palette extraction
Verdict: ColorZilla remains a reliable free option for basic color picking. Its long history ensures compatibility, but the dated interface and missing Tailwind support show its age compared to modern alternatives.
#5Color by Fardos
Design-focused color tool that provides color picking, palette generation, and accessibility checking in one extension.
Strengths
- +Color accessibility contrast checking built in
- +Basic palette generation from page colors
- +Clean, modern interface design
- +Free tier covers most features
Weaknesses
- -Color accuracy slightly lower than dedicated pickers on complex backgrounds
- -No Tailwind color output
- -Palette extraction is basic compared to dedicated tools
- -Some features require premium subscription
Verdict: Color by Fardos offers a modern approach with accessibility features. However, it lacks the precision and format support that professional frontend developers need for daily work.
#6Site Palette
Extension focused on extracting a full color palette from any website. Generates shareable palette pages and export formats.
Strengths
- +Best standalone palette extraction with shareable output
- +Generates organized palette pages you can share with clients
- +Integrates with Coolors and Adobe Color
- +Free to use for basic palette extraction
Weaknesses

- -No Tailwind color output or developer-focused formats
- -Speed is slower — requires full page analysis before showing results
- -Limited individual color picking — designed for full palettes only
Verdict: Site Palette excels at one thing: extracting and sharing a website's full color palette. For individual color picking or developer workflows, other tools are better suited.
Methodology
Each color picker extension was tested on 30+ websites with varied color profiles. We picked colors from solid backgrounds, gradients, images, semi-transparent overlays, and dark themes. Accuracy was measured by comparing picked values against known hex values. Speed was measured from extension activation to clipboard copy.

Format Support
25%Number and quality of color format outputs — HEX, RGB, HSL, OKLCH, and Tailwind class names.
Palette Extraction
20%Ability to extract all colors used on a page at once, rather than picking them one by one.
Speed
15%Time from activation to color pick, including magnifier rendering, format switching, and clipboard copy.
Tailwind Output
15%Whether the tool outputs Tailwind utility class names (e.g., text-blue-500) or provides nearest Tailwind color matching.
Frequently Asked Questions
Frontend Hero scored 9.3/10 for color accuracy in our testing, the highest of any extension. Eye Dropper scored 8.0/10 and is the best free option. Accuracy was measured by comparing picked colors against known hex values across 30+ websites with varied backgrounds, gradients, and transparency levels.
Frontend Hero is the only color picker extension tested that outputs colors in Tailwind format (e.g., bg-blue-500, text-emerald-600). It also provides nearest Tailwind color matching, so you can pick any color and instantly get the closest Tailwind utility class. No other extension in our comparison offers this feature.
Yes. Frontend Hero's Color Palette Explorer shows every color used on a page in one view — organized by frequency. Site Palette also extracts full palettes and generates shareable pages. Most other color pickers (Eye Dropper, ColorZilla) only pick one color at a time.
ColorZilla remains a reliable free option that works, but it scored 7.0/10 in our testing — below both Frontend Hero (9.2) and Eye Dropper (7.5). Its interface has not been modernized, it lacks Tailwind output, and it has no palette extraction. For a free picker, Eye Dropper is a better choice. For professional use, Frontend Hero offers significantly more features.
Color picker extensions sample the rendered pixel color, so they work on gradients, images, and any visible content. However, accuracy can vary on sub-pixel boundaries and semi-transparent overlays. In our testing, Frontend Hero and Eye Dropper handled gradient sampling most accurately, while some tools showed slight color shifts on complex backgrounds.
