# Extract colours from an image

Pull the dominant colours out of an image as a palette.

## How it works

Extracts the dominant colours from an image and shows them as a palette with hex values and contrast figures.

Colours are clustered rather than simply counted. Counting exact pixel values gives a useless answer, because a photograph of a blue sky contains thousands of slightly different blues and none of them individually dominates. Grouping similar colours and reporting cluster centres is what produces a palette anyone would recognise as the image’s colours.

The most common colour is often not the most useful one. Photographs are usually dominated by a large neutral area — sky, wall, background — while the colour that characterises the image is a smaller, more saturated region. The palette is ordered by prominence but the interesting entry is frequently second or third.

## Common questions

### Why is the dominant colour a dull grey?

Because large neutral areas — sky, walls, background — usually occupy the most pixels. The colour that characterises an image is often the second or third entry.

### How are the colours chosen?

By clustering similar pixels and reporting cluster centres. Counting exact values would return thousands of near-identical shades and no useful answer.
