How does the Image Color Story extract a palette?
It downsamples your image to 100×100 pixels in memory, samples every fourth pixel to get a representative spread of colors, then runs a lightweight k-means clustering with k=8. The eight cluster centers become your palette. Finally the tool sorts them by an "interestingness" score that favors saturated mid-luminance colors, which tend to be the visually defining tones rather than dominant grays or near-blacks.
Is my image sent anywhere?
No. The entire pipeline - file reading, downsampling, clustering, and rendering - happens inside your browser using the HTML Canvas API. The image never leaves your device, and there is no server component. You can use this tool offline once the page is loaded, and it works identically whether you are connected to the internet or not.
How is the mood label decided?
The tool computes the average hue, saturation, and luminance of your palette. Low-luminance images get tagged "Dark / Moody". Low-saturation images become "Minimal / Editorial". Otherwise the average hue picks the band: red/orange is "Energetic", yellow is "Sunny / Optimistic", green is "Calm / Natural", blue is "Trustworthy / Professional", purple is "Creative / Luxurious", and pink/magenta is "Playful / Romantic". It is a heuristic, so think of it as a starting prompt rather than a definitive judgement.
How accurate is the palette?
Very accurate for design and moodboard purposes. Because we cluster real pixel data rather than guessing from histograms, the palette reflects what is actually in the image. The eight-color cap is deliberate: a smaller palette is more useful for branding decisions than a long tail of slight variations. If your image has lots of similar tones, you may see clusters that are visibly close - that is normal and reflects the source material.
Can I copy the palette into my code?
Yes. Each swatch is one click to copy its HEX value. Below the palette you will find two ready-made snippets: a CSS custom-properties block (--color-1 through --color-8) and a Tailwind theme.extend.colors snippet (palette-1 through palette-8). Both have a "Copy" button. Paste them straight into your stylesheet or tailwind.config.js.
What image formats does it accept?
Any image format your browser can decode: PNG, JPG/JPEG, WebP, GIF, and AVIF in modern browsers. The tool only looks at the first frame of an animation. Very large images are handled fine because they get downsampled to 100×100 before clustering, so the analysis is fast even for multi-megabyte JPGs.
