100% In-Browser Color Extraction

Image Color Palette Extractor & Eyedropper Studio Pro

Q: How does the dominant color clustering algorithm work?

The system downsamples the image and maps pixels into 3D RGB color space, clustering nearby vectors using Euclidean distance metrics to isolate dominant hues.

Q: Are my images ever uploaded to a remote server?

Never. All image rendering and color calculations run 100% in local browser memory with zero network uploads.

Extract dominant color palettes using in-memory color quantization. Features an interactive pixel-level magnifier eyedropper and 1-click export to CSS variables, Tailwind, and JSON.

Why In-Browser Color Palette Extraction is Faster & More Precise

Extracting a cohesive color scheme from reference photography is a fundamental workflow for UI/UX designers and brand creators. Traditionally, developers had to import images into heavy graphics suites and manually pick individual swatch points.

PhuDuy Tools Palette Extractor runs an in-memory color quantization algorithm over HTML5 Canvas downsamples. It analyzes thousands of pixels in milliseconds to cluster the top 6-10 dominant color harmonies, complete with percentage shares, a 4x pixel magnifier loupe, and instant export to CSS Variables, Tailwind config, or JSON.

3 Easy Steps to Extract Color Palettes

🖼️

1. Upload Image

Drop any inspirational photograph, logo mockup, or brand asset.

🔍

2. Inspect with Loupe

Hover over any detail with the 4x pixel loupe and click to grab exact hex values.

💻

3. Copy Palette Tokens

Copy HEX/RGB values or export ready-to-use CSS Variables and Tailwind themes.

Frequently Asked Questions (FAQ)

How does the dominant color clustering algorithm work? ▼

The system downsamples the image and maps pixels into 3D RGB color space, clustering nearby vectors using Euclidean distance metrics and sorting by cluster density to isolate visually dominant hues.

Are my images ever uploaded to a remote server? ▼

Never. All image rendering and color calculations run 100% in local browser memory with zero network uploads.

Can I pick colors from anywhere on my desktop? ▼

On modern browsers supporting the native EyeDropper API (Chrome and Edge), you can click "Screen Eyedropper" to sample colors from any external application on your desktop.
