How to get the color palette images?
Use the free website Palette Generator , which does not require mandatory registration and allows you to upload a list of images.
The service uses the k-means algorithm to determine the predominant colors in an image. Their number is displayed in the range from 2 to 10 colors.
By default, the predominant colors are determined throughout the image, but when you click on the button “Change the sample” you can select a specific area.
