# Subtractive Mix

Subtracts foreground from background values.

## Overview

Overview B - F Parameter Types Parameter descriptions Discussion The Subtractive Mix node subtracts two inputs and uses the Mix input to determine the weight of the foreground in the blend, represented by the equation B - F. Higher values closer to 1 output a more intense subtractive mix, while lower values closer to 0 dim the effect. Below is an example of a simple node graph that uses the subtractive mix node to blend two images into a single material:

Below are two images and the resulting blended texture applied to a cube:
