When a pin catches your eye, its colors are often doing most of the work. This tool finds the 5 to 8 colors that cover most of an image and lists them from most used to least, with hex codes you can copy into any design app. It also suggests which color to use as a background, which as the title and which as an accent, and checks that the title will be readable.
The palette is calculated in your browser from a small copy of your image, so it is fast and nothing is uploaded. You can download the palette as a pin-sized image for your mood board, or open the colors straight in the pin maker.
How the colors are found
The image is scaled down to about 120 pixels on its long side, then every pixel is grouped with the colors closest to it using k-means clustering. Each group becomes one swatch, and the list is sorted by how much of the image it covers. Transparent pixels are ignored, so logos and cut-outs work too.
Because the colors are averages of similar pixels, a small but striking detail may merge into a nearby color. If an accent you care about is missing, raise the number of colors. To copy the whole look of a pin, including its layout, try the pin style copier.
Building a pin palette that stays readable
A good pin palette has one calm background color, one title color with strong contrast against it, and one accent for a highlighted word or a button. The contrast note under the color pickers uses the same contrast ratio as web accessibility guidelines; 4.5:1 or more reads comfortably at feed size.
Keep your palette consistent across pins so people recognize your work in the feed. The pin maker can save it as a brand kit, and the mood board maker is handy for collecting inspiration.
