Material.SetColor

설명

Set a named color value.

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

When setting color values on materials using the Standard Shader, you should be aware that you may need to use EnableKeyword to enable features of the shader that were not previously in use. For more detail, read Accessing Materials via Script.

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).
"_EmissionColor" is the emissive color of a material (used in vertexlit shaders).
"_ReflectColor" is the reflection color of the material (used in reflective shaders).
