Privacy and File Processing
Color Extractor keeps its Browser-decodable image files input in browser memory while the operation runs. The workflow creates HEX swatches, or JSON palette for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs
Input
- Browser-decodable image files
Output
- HEX swatches
- JSON palette
Quality and Fidelity
Palette colors are representative samples, not a color-managed proof. Resizing during analysis, lighting, compression, profiles, and gradients can influence the selected swatches.
Limitations and Important Notes
- Extracted colors are approximate dominant samples.
- Transparent pixels and subtle gradients may not appear as separate swatches.
- The tool does not validate accessibility contrast automatically.
Worked Example
Use a representative source image, apply Color Extractor, and compare the result with the original at full size before publishing it.
Helpful Tips
- Keep the untouched source image while evaluating Color Extractor.
- Check the HEX swatches or JSON palette result at its intended display size.
