How do I extract exact HEX and RGB color codes from an image?
An image color picker reads raw RGBA pixel data directly from an HTML5 canvas using the getImageData() method, which returns an 8-bit unsigned integer array of Red, Green, Blue, and Alpha values (0–255). Converting RGB to HEX uses: HEX = '#' + ((1 << 24) + (r << 16) + (g << 8) + b).toString(16).slice(1). IMAZEOO also clusters pixels to automatically extract the dominant 6-color palette.
Key Takeaways
- Inspect any pixel to extract exact HEX (#FFFFFF), RGB, and HSL color codes.
- Automatic dominant color palette clustering (extracts top 6 harmonious colors).
- One-click clipboard copying for seamless workflow into CSS, Tailwind, or Figma.
- 100% private: Image analysis executes completely in your local browser memory.
