Palette extract read the image and generate palette from it. Note that this node can cause performance issue if the image is too large.

Algorithms

The first step is to extract all colors from the images, then we can use different algorithms to reduce the number of colors. The available algorithms are:

K-mean

K-mean is a simple algorithm that can be used to cluster data. When select this algorithm you can choose what color space to use, and how many colors to extract.

Frequency

Frequency algorithm simply count the frequency of each color and return the most frequent colors based on the Max Colors value.

All colors

Return all colors found in the image.
