Color Palette Extractor
Upload an image and extract the dominant color palette. Get hex codes, check WCAG contrast compliance, and copy colors for your designs.
Color is the first thing the eye resolves in a feed scroll, before text, before composition, before the product. Knowing the dominant palette of an ad tells you whether it will stand out against the surrounding feed (low-contrast ads get scrolled past) and whether the CTA copy stays legible on small mobile screens. This extractor pulls the top five dominant hex codes from any image using a median-cut clustering algorithm that runs in the browser via the Canvas API.
Creative strategists use it for competitive audits, drop a screenshot of a competitor ad and you get their palette instantly, useful for mood boards and briefing generative image models. Designers use it to match landing page colors to the hero ad creative. Brand managers use it to flag WCAG contrast failures before a campaign launches; a CTA button at 3.2:1 contrast looks fine on desktop and disappears on an iPhone in sunlight.
Everything runs client-side, safe for unreleased campaigns, confidential brand assets, and competitive intelligence work.
