Free Color Palette Extractor from Image — Get HEX, RGB & HSL Online

Last Updated: May 2026  ·  5 min read

Whether you're a designer trying to match a brand's colors, a developer building a theme, or a marketer creating consistent visual assets, extracting the exact colors from an image is an essential skill. Our free color palette extractor uploads nothing to servers — it runs entirely in your browser using the Canvas API — and gives you HEX, RGB, and HSL codes for up to 20 dominant colors. No signup, no limits.


What Is a Color Palette Extractor?

A color palette extractor analyzes the pixels in an image and identifies its most prominent, distinct colors. Instead of manually eyedropping individual pixels, the extractor does the work for you — giving you a curated set of colors that represent the image's overall palette.

This is useful for: - Brand identity: Extract colors from a logo to build a style guide - Web design: Match a hero image's colors to your page's color scheme - Product photography: Identify dominant colors for filtering/tagging - Data visualization: Choose colors that complement your charts and graphs - Interior design: Extract colors from inspiration photos - Fashion/print design: Build cohesive palettes from reference images


How the Color Extraction Works

Our tool uses a median cut quantization algorithm — a classic computer graphics technique:

  1. Sample pixels: The image is drawn to an HTML Canvas element and pixel data is read
  2. Filter transparent pixels: Pixels with very low alpha values are excluded
  3. Bucket creation: Pixels are placed in a single bucket and split repeatedly along the axis with the widest color range
  4. Averaging: The average color of each bucket becomes one palette color
  5. Sort by lightness: Colors are sorted from lightest to darkest for easy scanning

For privacy, your image never leaves your browser. All processing happens locally using the Web Canvas API (getImageData).


Color Format Reference

HEX

#2D2B6F

The most common format for web development. 6 hexadecimal digits representing red, green, blue channels. Used in CSS, HTML, and most design tools.

RGB

rgb(45, 43, 111)

Red-Green-Blue values from 0–255. Used in CSS, image editing software, and color pickers.

HSL

hsl(242, 44%, 30%)

Hue (0–360°), Saturation (0–100%), Lightness (0–100%). Most human-readable format. Hue describes the color family, saturation the intensity, and lightness the brightness.


When to Use Each Format

Use Case Best Format
CSS stylesheets HEX or HSL
CSS custom properties / design tokens HSL
Image editors (Photoshop, Figma) HEX or RGB
JavaScript canvas drawing rgb() or HEX
Color manipulation (tinting, shading) HSL
Database storage HEX (compact)

Building a Design System from an Image

Here's a workflow for extracting and using colors professionally:

Step 1: Extract 6–8 colors from your brand image Use our free extractor to identify primary, secondary, and accent colors.

Step 2: Export as CSS custom properties Click "Export as CSS" to copy:

:root {
  --color-1: #2D2B6F;
  --color-2: #D4B8CC;
  --color-3: #1A1832;
  --color-4: #6B5EA8;
}

Step 3: Name your tokens Rename the generic names to semantic ones:

:root {
  --color-primary: #2D2B6F;
  --color-secondary: #D4B8CC;
  --color-background: #1A1832;
  --color-accent: #6B5EA8;
}

Step 4: Create tints and shades using HSL Use HSL to create lighter and darker variants:

--color-primary-light: hsl(242, 44%, 45%);
--color-primary-dark:  hsl(242, 44%, 20%);

Color Harmony Principles

Once you have your base colors, consider these harmony rules:

Harmony Description Example
Monochromatic One hue, different lightness/saturation Navy → blue → sky blue
Analogous Adjacent hues on the color wheel Blue, blue-purple, purple
Complementary Opposite hues Blue and orange
Triadic Three evenly-spaced hues Red, yellow, blue
Split-complementary Base color + two adjacent to its complement Blue, orange-red, orange-yellow

Export Options

Our free color palette extractor supports three export formats:

CSS Custom Properties:

Frequently Asked Questions

How do I extract colors from an image? Upload your image to the SolutionGigs Color Palette Extractor, and it will automatically identify the dominant colors and display their HEX, RGB, and HSL values. No account or sign-up needed.

What is a HEX color code? A HEX color code is a 6-character value (like #2d2b6f) that represents a specific color using hexadecimal numbers. It's the most widely used format in web design, CSS, and design tools like Figma.

How many colors can the tool extract? The Color Palette Extractor identifies up to 20 dominant colors from your image, sorted by frequency of appearance. Most palettes show 6–10 meaningful colors.

Is my image uploaded to a server? No — color extraction runs entirely in your browser using the HTML Canvas API. Your image is never sent to any server, ensuring complete privacy.

What color format should I use for web design? HEX (#rrggbb) is standard in CSS and most design tools. Use RGB when you need to control opacity (rgba). Use HSL when adjusting hue or brightness programmatically — it's the most human-intuitive format.
