SetColor(propertyName: string, color: Color): void;

void SetColor(string propertyName, Color color);

def SetColor(propertyName as string, color as Color) as void

SetColor(nameID: int, color: Color): void;

void SetColor(int nameID, Color color);

def SetColor(nameID as int, color as Color) as void

Description

Set a named color value.

Many shaders use more than one color. Use SetColor to change the propertyName color.

Common color names used by Unity's builtin shaders:
"_Color" is the main color of a material. This can also be accessed via color property.
"_SpecColor" is the specular color of a material (used in specular/vertexlit shaders).
"_Emission" is the emissive color of a material (used in vertexlit shaders).
"_ReflectColor" is the reflection color of the material (used in reflective shaders).
