About this tool

Pull the key colours out of a photo. This extractor analyses an image in your browser, quantising its pixels to find the dominant tones and a set of complementary accent swatches, and — usefully for design work — rates each colour’s WCAG AA and AAA contrast against both white and black text.

That makes it more than a colour grabber: it tells you not only which colours a photo contains but whether they can carry text accessibly, which is exactly what you need when building a palette or a UI around an image. You get hex swatches ready to use and an at-a-glance accessibility read on each.

Because the analysis is done client-side by sampling the image on a canvas, the photo is never uploaded — you can extract palettes from private or unpublished images safely. Use it to derive a brand palette from a hero photo, match UI colours to imagery, or find an accent that already lives in a picture.

Frequently asked questions

How does it find the colours in an image?
It samples the image on a canvas in your browser and quantises the pixels to identify the dominant tones and complementary accent colours.
What do the contrast ratings tell me?
For each extracted colour it shows WCAG AA and AAA contrast against white and black, so you can see whether a colour is usable for text and meets accessibility thresholds.
Is my image uploaded?
No. The analysis is done client-side, so the photo never leaves your device — safe for private or unpublished images.
What can I use the extracted palette for?
Building a brand or UI palette from a photo, matching interface colours to imagery, or finding an accent colour that already appears in a picture.
What format are the colours given in?
As hex swatches you can copy directly into your CSS or design tool.
