Why Generate Palettes?
Extracting palettes from images is useful for:
- Design Inspiration: Finding harmonious colors based on a photo.
- Branding: Creating a color scheme that matches product or lifestyle imagery.
- UI Design: Developing themes that complement illustrative assets.
- Data Visualization: Selecting colors that reflect the subject matter.
- Art & Craft: Matching paint, thread, or fabric colors.
How It Works
This tool analyzes the pixels of your uploaded image directly in your browser:
- The image is downsampled for performance.
- Pixels are sampled to gather color data.
- A K-Means clustering algorithm groups similar colors together.
- The center (average color) of each cluster forms the palette.
- Multiple palettes with different numbers of colors are generated.
- Palettes are sorted by luminance (darkest to lightest).
No image data is sent to any server. All processing happens locally.
Frequently Asked Questions
Why are the palettes different sizes?
Images contain varying levels of color complexity. Generating palettes of different sizes (e.g., 5, 8, 12 colors) provides options, from capturing the most dominant colors (smaller palettes) to including more subtle secondary themes (larger palettes).
Why don't the palette colors exactly match tiny details in the image?
The K-Means algorithm finds the *average* color within dominant color groups. It's excellent for capturing the overall theme and major colors but might average out very small, distinct color spots or fine gradients into a representative mean color for that cluster.
Why did I get an error loading an image URL?
This often happens due to CORS (Cross-Origin Resource Sharing) restrictions set by the website hosting the image. They may prevent other websites (like this tool) from directly accessing their images. If you encounter this, try downloading the image and uploading it as a file instead.
Is there a limit on image size?
While the tool suggests a 10MB upload limit, the primary performance constraint is the image's dimensions (width x height). Very large images take longer to process client-side. The tool automatically downsamples the image before analysis to improve speed.
