Image colour palette extractor

What this tool does

The image is drawn at 48×48, colours are quantised into buckets, and the most frequent buckets become hex values. Transparent pixels are ignored.

How to use it

1. Drop an image.
2. Copy hex values.
3. Treat them as starting points, not brand-official colours.

Troubleshooting

The palette is muddy

The photo may be noisy. Crop to the object you care about and extract again.

FAQ

Is this k-means?

No. It is histogram bucketing on a tiny preview. It is fast and good enough for picking UI colours from a screenshot.

Are colours shown as executable CSS?

They are text. You copy them. They are not injected as a stylesheet from the file.

Does it work on GIF animation?

It samples whatever frame the browser draws, usually the first.

Can I choose 20 colours?

This version returns up to six, which stays readable on a phone.
