How to read and refine the output
A small palette highlights the broad visual identity of the image. A larger palette captures secondary accents and subtle variations. Very similar swatches usually indicate that the source uses a narrow tonal range.
Practical advice
Tips for better results
- Use representative, correctly exposed images.
- Choose five or six colors for a practical UI palette.
- Check color contrast before using pairs for text.
- Remove large neutral borders before extraction.
Important limitations
What this tool cannot guarantee
Dominant colors are calculated from pixel frequency, so a large background can outweigh a small but important accent. The result is a design aid, not an accessibility or color-management certification.
Common questions
Color Palette Extractor FAQs
How are dominant colors calculated?
The tool samples pixels and groups nearby RGB values using a lightweight clustering algorithm.
Can I copy all colors as CSS?
Yes. The tool creates CSS custom-property lines for the generated palette.
Why is the background color listed first?
Large image regions contribute more pixels and are therefore often dominant.
Does it support transparent PNG files?
Yes. Fully transparent pixels are ignored during palette analysis.
