What Is a Color Picker?
A color picker (or eyedropper tool) lets you click on any pixel in an image to extract its exact color value. The color is returned in common formats like HEX, RGB, and HSL so you can use it directly in code, design tools, or print specifications.
Color extraction is essential in design workflows — whether you're matching a brand color from a screenshot, sampling a palette from a photograph, or identifying the exact shade used in a UI mockup.

Pick a Color →When To Use Color Extraction
Extracting colors from images is valuable in many design and development workflows:
- Brand matching — sample exact colors from a company logo or style guide image to use consistently in your designs and CSS
- Web development — pick colors from a design mockup or screenshot and get CSS-ready HEX or RGB values instantly
- Art and illustration — sample harmonious colors from photographs or paintings to build realistic color palettes for your own work
Frequently Asked Questions
What color formats are supported?
The tool displays each picked color in three formats: HEX (e.g., #3b82f6), RGB (e.g., rgb(59, 130, 246)), and HSL (e.g., hsl(217, 91%, 60%)). All three can be copied to clipboard with one click.
Is there a limit to how many colors I can pick?
No. You can pick as many colors as you like. The last 10 colors are displayed in a history panel so you can compare and reuse them without re-sampling.
Is my image uploaded to a server?
No. All processing happens locally in your browser using the Canvas API. Your image never leaves your device.
