A secure, client-side color extraction engine built for modern UI designers and web developers.
At ColorPicker.Codes, our mission is to build highly functional, privacy-first web utilities for digital creators. We believe that professional design resources should be fast, accessible, and run entirely within the user's control. By eliminating server-side uploads and intrusive ads, we help designers and developers build beautiful interfaces more efficiently.
We believe the web should be built on open protocols. Our goal is to provide a comprehensive, all-in-one color extraction tool that matches the performance of desktop software while running directly in a web browser. From identifying color names to testing accessibility contrast, we build tools that simplify your design workflow.
ColorPicker.Codes was created by a small team of frontend developers and UI/UX designers who were frustrated by the limitations of existing online color tools. Many websites we used were laden with heavy ads, required slow file uploads to remote databases, or lacked advanced features like accessibility checking and palette history.
We wanted a tool that was fast, private, and worked offline. To achieve this, we developed a color extraction system using HTML5 canvas APIs to process image pixels locally in the browser. This approach ensures your files never leave your machine, providing a secure and private environment for your projects. What started as an internal tool has grown into a platform used by thousands of creative professionals worldwide.
ColorPicker.Codes is built on a modern frontend stack using HTML5, CSS3, and vanilla JavaScript, ensuring fast load times and smooth performance across all devices. We use canvas APIs for pixel-level color sampling and custom color quantization algorithms to extract the top 10 dominant colors from any image.
When you select an image, our tool draws it onto a canvas element. This lets us sample individual pixel coordinates on hover or click, translating them into HEX, RGB, HSL, HSV, and CMYK formats. The entire process runs locally in your browser, keeping your data secure and private.
To extract dominant colors, our tool downsamples images and groups similar pixels using an RGB Euclidean distance threshold. This groups similar colors together and selects the most frequent ones, resulting in a diverse, non-repetitive palette that captures the true color profile of your image.
Our accessibility checker calculates relative luminance using formulas from the WCAG 2.1 Web Content Accessibility Guidelines. By checking the contrast ratio between your selected color and white or black text, we provide clear AA and AAA ratings to help you design readable, accessible interfaces.
ColorPicker.Codes is designed to offer a faster, more secure alternative to traditional online color tools:
We are constantly working to improve ColorPicker.Codes by adding features that support your creative workflow. Future updates will include advanced palette sorting, SVG color extraction, and integrations with popular design tools like Figma and Adobe XD. We want to keep building tools that help you create beautiful, accessible, and user-friendly designs.
