Blend Colors is a utility node that allows you to blend together two input colors or textures, using a third value to control the blend.

The color of the output is determined by the Blender attribute, which can range from 0 to 1. When Blender is 1, the Output is set to Color 1. When Blender is 0, Output is set to Color 2. When Blender is 0.5, Output is an equal mix of the two colors.

By applying a texture map to Blender (say, an image of white text on a black background) you can create a shader that uses Color 1 for the text, and Color 2 for the background.

Here is the formula used for color blending:

Output[i] = Color1[i] * Blender[i] + Color2[i] * (1.0 - Blender[i])

In the table below, important attributes have their names listed in bold in the description column.

Long name (short name)	Type	Default	Flags
blender (b)	float	0.5
Blender controls how much of each of the input colors is mixed into the final Output. As Blender increases, you see more of Color 1 and less of Color 2. As it decreases, you see more of Color 2 and less of Color 1.
color1 (c1)	float3	1.0, 0.0, 0.0
Color 1 is the first input color.
color1R (c1r) float 0.0 The red component of Color 1
color1G (c1g) float 0.0 The green component of Color 1
color1B (c1b) float 0.0 The blue component of Color 1
color2 (c2)	float3	0.0, 0.0, 1.0
Color 2 is the second input color.
color2R (c2r) float 0.0 The red component of Color 2
color2G (c2g) float 0.0 The green component of Color 2
color2B (c2b) float 0.0 The blue component of Color 2
output (op)	float3	0.0, 0.0, 0.0
Output is the final blended color.
outputR (opr) float 0.0 The X component of Output
outputG (opg) float 0.0 The Y component of Output
outputB (opb) float 0.0 The Z component of Output
