# Vertex-color blending
The following sections contain examples on how to blend colors using vertex-colors. It is recommended to read Shading network concepts before proceeding.
# Vertex-color blending using InterpolateNode
This script sets up three vertex color nodes where the last one is used as blend weight. This example is based on the InterpolateNode.
