What color formats does the online color picker output?

The color picker outputs four formats for every sampled color: HEX (e.g., #3A7BD5) — the standard format for web CSS and design tools; RGB (e.g., rgb(58, 123, 213)) — red/green/blue values from 0–255 used in CSS and coding; HSL (e.g., hsl(216, 63%, 53%)) — hue/saturation/lightness, useful for systematic color adjustments in UI design; and CMYK (e.g., cmyk(73, 42, 0, 16)) — cyan/magenta/yellow/key used for print production. All values are displayed simultaneously, and each can be copied to clipboard with a single click.

How does the dominant color palette extraction work?

The palette extractor analyzes all pixel color values in the image and applies a median cut quantization algorithm to group similar colors together and identify the most representative hues. The result is 4–8 dominant colors that capture the visual character of the image — typically including the primary subject color, background color, and key accent tones. This is not an averaging operation (which would produce muddy mid-tones) but a true representation of the image's distinct color populations.

Can I use the color picker to match colors from a client logo for CSS?

Yes — this is one of the most common use cases. Upload the logo PNG or SVG, use the eyedropper to click on each brand color in the logo, and copy the HEX or RGB values directly into your CSS variables or design token file. For logos with anti-aliased edges, sample from the solid center of each color area rather than the edge pixels, which may blend with the background and produce inaccurate values. Use the built-in zoom view to precisely select the right pixel, especially for small logo elements.

About

Online Color Picker With HEX RGB HSL CMYK Output From Images

Identifying exact color values from photographs, screenshots, logos, and design mockups is a fundamental workflow in UI/UX design, brand identity work, and web development. Our browser-based color picker gives you a precision eyedropper to sample any pixel in an uploaded image and instantly outputs the color in HEX, RGB, HSL, and CMYK formats — all formats you need across different design and print workflows.

Beyond single-pixel sampling, the tool automatically extracts a dominant color palette from the entire image — up to 8 representative colors that capture the image's visual character. This palette extraction is invaluable for building color schemes from brand photography, creating consistent UI color tokens from a logo, or generating a color palette for a website redesign based on source imagery.

All processing happens in the browser using the HTML5 Canvas API and client-side JavaScript. Images are never transmitted to a server, making the tool safe for use with confidential mockups, unreleased product photography, and proprietary design assets.

What makes it unique

Automatic Dominant Color Palette Extraction From Any Image

Beyond the eyedropper, the color picker uses a median cut quantization algorithm to analyze pixel distribution across the entire image and identify 4–8 dominant colors that best represent the image's color story. This palette is displayed with HEX codes you can copy in one click. Use it to extract brand colors from photography, build a color scheme from an existing design reference, or identify the key hues in competitor brand imagery for analysis.

Common Use Cases for the Color Picker

Brand Color Extraction

Extract precise HEX/RGB values from brand photography, logos, or product imagery to create consistent color tokens for a design system or brand style guide.

UI Design Color Matching

Sample colors from a client-supplied mockup or screenshot to ensure your CSS color values exactly match the original design specification without guessing.

Print and CMYK Color Workflows

Convert image colors to CMYK for use in print production workflows, ensuring color accuracy when moving artwork from screen to press.

How to Use

1
Upload an Image
Drag and drop or select any image file (JPEG, PNG, WebP, GIF, SVG). The image renders in the canvas panel — nothing is uploaded to any server.
2
Use the Eyedropper to Sample Colors
Hover over the image in the canvas panel. A magnified zoom view shows the pixel under your cursor. Click any pixel to sample its exact color and view HEX, RGB, HSL, and CMYK values instantly.
3
Copy Values and Explore Palette
Click any color format value to copy it to clipboard. Scroll to the palette section to see the auto-extracted dominant colors and copy any of those values as well.

Features

Precision Eyedropper With Zoom
Magnified zoom view around the cursor shows individual pixels clearly, enabling precise color sampling from high-resolution images without squinting at small details.
HEX, RGB, HSL, and CMYK Output
Every sampled color is instantly displayed in all four major color formats with one-click copy — covering web, design, and print workflow requirements.
Dominant Palette Extraction
Automatically extracts 4–8 dominant colors from the full image using quantization analysis, producing a representive palette with copyable HEX codes.
All Image Formats Supported
Accepts JPEG, PNG, WebP, GIF, BMP, and SVG images. Rendered in HTML Canvas for pixel-perfect color sampling at any zoom level.
