About Client-Side Color Extraction
SuperUtility offers an offline-first Color Picker from Image designed for developers, graphic designers, and branding specialists. Selecting precise brand colors or sampling palette colors from design files is essential to keeping visuals cohesive.
Our color picker tool allows you to upload any local image file, and rendering it inside a canvas element. Simply hover or click over any section of the image to extract its exact pixel color data. Everything operates offline in-browser, preventing leakage of proprietary designs.
Frequently Asked Questions
How are the color values extracted?
When you hover or click on the canvas, we get standard canvas coordinates and fetch the color data utilizing the browser's built-in `getImageData(x, y, 1, 1).data` API, which extracts pure red, green, blue, and alpha ratios.
Is my uploaded design graphic secure?
Yes, 100% secure. Because SuperUtility runs entirely locally in your own browser's memory, your design files, graphics, or proprietary screenshot assets never touch any remote servers.
