Overview

Extract the Dominant Colors from an image with this Substance Designer (2018.3.x) node. Perfect for quickly generating color palettes or extracting colors to use in your graphs. 

Modes

The default mode is used to visualize the input image’s dominant colors. The node also outputs each extracted colors individually so you can easily use them in a graph.

Graph

This mode graphs the input image’s dominant colors, weighted by importance.

Quantize

How it Works

The node is based on the K-Means Clustering algorithm, which as the name suggests, is used to cluster similar data points together. Various Color Difference equations can be used in order to determine how similar the pixels are to each other.
