Replace Color node

The Replace Color node replaces a color in the input with another color.

Ports

Name	Direction	Type	Binding	Description
In	Input	Vector 3	None	Sets the input you want to replace a color in. For example, a texture.
From	Input	Vector 3	Color	Sets the color to replace.
To	Input	Vector 3	Color	Sets the color to replace From with.
Range	Input	Float	None	Sets the range around From to replace. For example, if you set From to (0, 0, 0) and Range to 0.1, Unity replaces colors from (0, 0, 0) to (0.1, 0.1, 0.1) with To.
Fuzziness	Input	Float	None	Sets how much to soften the boundary between the replaced color and the rest of the colors.
Out	Output	Vector 3	None	The In input, with the From color replaced with the To color.

Generated code example

The following example code represents one possible outcome of this node.

void Unity_ReplaceColor_float(float3 In, float3 From, float3 To, float Range, float Fuzziness, out float3 Out)
{
    float Distance = distance(From, In);

    // Use max to avoid division by zero
    Out = lerp(To, In, saturate((Distance - Range) / max(Fuzziness, 1e-5f)));
}
