About Eurika ColorStudio
Eurika ColorStudio is an all-in-one browser utility designed for developers, designers, and creatives. Instead of jumping between multiple tabs to extract colors, build gradients, and convert formats, we've unified the workflow into a single, high-performance toolkit.
Image Palette Extractor
Need to match a design to a specific photograph or brand asset? Drag and drop any image into the Palette Extractor. Our zero-dependency, local algorithm instantly analyzes the image and returns the dominant color palette. Because it runs entirely in your browser using HTML5 Canvas, your images are never uploaded to any server.
CSS Gradient Builder
Building the perfect linear gradient can be tricky by hand. The Gradient Builder provides a visual interface to manage multiple color stops and angles. You can even copy a color from the Palette Extractor and paste it directly into your gradient stops. Once you're satisfied, copy the production-ready CSS rule with one click.
Advanced Color Picker
A streamlined tool for precise color selection and conversion. Pick any color using your operating system's native interface (or use its eyedropper tool), and instantly receive the HEX, RGB, and HSL formats.
Zero Data Collection & Privacy
Like all tools in the Eurika suite, ColorStudio processes everything locally on your device. We do not store your images, palettes, or track your usage.
