Overview

The Color Palette Extractor from Image URL allows you to fetch any remote image via its direct URL, extract its dominant colors, and instantly generate a downloadable palette package containing CSS variables, Tailwind configurations, JSON, ASE, and ACO files, alongside contrast ratio evaluations.

When to use

  • When you need to extract a cohesive color scheme directly from a live web image or CDN asset without downloading the image first.
  • When building design systems and you require instant, code-ready formats like Tailwind configurations, CSS variables, or Adobe Swatch Exchange files.
  • When evaluating color contrast ratios of extracted colors to ensure accessibility compliance for digital interfaces.

How it works

  1. 1Paste the direct URL of a remote image into the input field and specify your desired palette size.
  2. 2The tool fetches the image, processes its pixels to extract the dominant color palette, and calculates contrast ratios.
  3. 3Download the generated package containing CSS, Tailwind, JSON, ASE, and ACO files for your design and development workflows.

Use cases

  • Extracting brand colors from a client's live website hero image to kickstart a UI redesign.
  • Generating Adobe ASE/ACO swatches from online mood boards for direct import into Photoshop or Illustrator.
  • Creating Tailwind and CSS variable files directly from product images hosted on a CDN.

Examples

1. Extracting a Launch Palette from a Hero Image

Frontend Developer

Background

A developer needs to quickly implement a landing page using the exact colors from a newly uploaded hero image on their staging server.

Problem

Manually color-picking pixels from the browser is slow and doesn't generate structured code configurations.

How to use

Paste the hero image URL into the Image URL field, set the palette size to 6, name the package 'launch-hero-palette', and click generate.

imageUrl: 'https://example.com/assets/hero.jpg', paletteSize: 6, exportPackageName: 'launch-hero-palette'

Outcome

The developer receives a downloadable zip containing CSS variables, Tailwind configurations, and ASE files, along with a contrast ratio preview.

2. Generating Brand Swatches from CDN Assets

UI/UX Designer

Background

A designer wants to create Adobe Illustrator swatches based on product photography hosted on the company's CDN.

Problem

Downloading images, importing them into design software, and manually creating swatches takes too much time.

How to use
