Color Picker from Image

About the Image Color Picker

This image color picker extracts exact color values from any uploaded photo, illustration, or screenshot. Upload an image, click any pixel to read its HEX, RGB, and HSL values, and let the tool automatically detect the dominant color palette — all without sending data to a server.

Designers use image color pickers to match brand colors from reference images, recreate palettes from photographs, or identify specific shades in mockups. Having extraction, conversion, and copy-to-clipboard in one place eliminates round-trips between a color sampler and a converter.

Key Features

• Click-to-pick on canvas — click any pixel on the uploaded image to capture its color instantly.
• Magnified loupe — an 11 x 11 pixel grid zoomed 12x follows your cursor, so you can target individual pixels even in detailed images.
• Automatic dominant palette — on upload, the tool analyzes the image and extracts six dominant colors using median-cut quantization.
• Multiple color formats — every picked or extracted color displays HEX, RGB, and HSL values. Click any value to copy it.
• Drag-and-drop or paste — drop an image file, choose one from the file picker, or paste from your clipboard.
• Client-side processing — the image never leaves your browser. All pixel reading and palette extraction run locally on your device.

How Does Color Extraction from an Image Work?

When you upload an image, the browser draws it onto an HTML canvas element. The canvas API exposes every pixel as raw RGBA data through getImageData(). Clicking a pixel reads the red, green, and blue channel values at that coordinate and converts them to standard color formats.

For the dominant palette, the tool downsamples the image to a 100 x 100 grid and applies the median-cut algorithm. Median-cut works by sorting pixels along the color channel with the widest range, splitting them at the median, and repeating until the desired number of color buckets exist. Each bucket averages its pixels to produce one representative color. The result is a concise palette that captures the image's visual character.

How to Use the Image Color Picker

1. Upload an image — drag a file onto the drop zone, click "Choose a file," or paste from your clipboard. PNG, JPEG, WebP, and SVG are supported.
2. Review the dominant palette — six extracted colors appear automatically above the canvas. Click any swatch to copy its HEX value.
3. Pick colors manually — hover over the image to see the loupe and current pixel color. Click to add the color to your picked list.
4. Copy color values — each picked color shows HEX, RGB, and HSL. Click any format to copy it to your clipboard.
5. Remove or clear — remove individual colors with the X button, or clear all picked colors at once.

Common Use Cases

• Brand color matching — extract exact colors from a client's logo or brand guide image to use in CSS or design tools.
• Photo-inspired palettes — pull a cohesive color scheme from a landscape, product photo, or artwork to inform a design project.
• UI color auditing — screenshot an interface and identify every color used, verifying consistency across elements.
• Illustration reference — sample specific shades from reference artwork to reproduce them accurately in digital painting.
• Social media design — match colors from an existing post or template to maintain visual consistency across content.

Frequently Asked Questions

Is my image data safe when I pick colors online?

Your image never leaves your device. The tool processes everything inside your browser using the HTML canvas API. No uploads, no server calls, no stored data.

What image formats can I extract colors from?

The tool accepts PNG, JPEG, WebP, and SVG files. Any image your browser can render will work on the canvas.

How accurate is the dominant color extraction?

The median-cut algorithm is a well-established quantization method that reliably captures the most visually prominent colors. It downsamples to 100 x 100 pixels for speed, which is sufficient for palette-level accuracy.

Can I pick colors from a screenshot?

Yes. Take a screenshot, then paste it directly into the tool with Ctrl+V (Cmd+V on Mac). The tool reads from the clipboard and loads the image onto the canvas immediately.

What is the difference between this tool and the screen color picker?

The screen color picker uses the browser EyeDropper API to sample any pixel visible on your display. This tool works with uploaded images — you get a persistent canvas, a magnified loupe, and automatic palette extraction.
