How to build a palette from a photo
A photo palette gives you colours that already work together, because they came from one scene. This guide explains sampling in plain terms.
What is the Color Palette from Image?
In the browser, this tool samples an uploaded image on a canvas and summarises its colours. Here it also shows the same averaging maths on sample pixels, so the palette logic is visible even without an image file.
How to use it
- Choose an image file in a browser.
- Set how many colours you want.
- Read the sampled palette and average tone.
Worked example
With no image in this run, the sample-pixel maths gives a warm average tone and requests five palette colours; in a browser a real upload replaces the sample.
What is image colour sampling?
It reads many pixels from a picture, groups similar ones, and keeps the most representative colours as a palette.
Frequently asked questions
Is my image uploaded?
No, browser sampling happens on your own device with a canvas.
Why does this run show a demo average?
Without a browser and a file, it exercises the same averaging maths on sample pixels so the logic stays checkable.
