Signifies that value of this property contains the main color of the Material.

This flag corresponds to the [MainColor] ShaderLab Properties attribute.

By default, Unity considers a color with the property name name "_Color" to be the main color. Use the [MainColor] ShaderLab Properties attribute to make Unity consider a color with a different property name to be the main color.
