About image colour extractor
A colour extractor finds the main colours in a photo and gives you their codes. Designers use it to build palettes from a logo, product or scene.
How dominant colours are found
The picture is reduced to a small set of representative colours by grouping similar pixels together. Colours that cover the biggest areas appear first. A photo with a busy background can give a different answer from the subject alone, so crop first if you care about one object.
Using the colours
Copy a HEX code into a design tool or CSS file. Check text contrast with the WCAG Contrast Checker before using a colour pair for text and background.
A worked example
A photo of a sunset might give five dominant colours: a deep orange, a pink, a purple, a dark blue and a near-black. Use them as the basis of a palette for a poster or a slide deck that matches the photo.
