Material Graph nodes colors

Why in the Material Editor Graph the nodes have different title colors and what these colors mean?

You have documentation here :Materials | Unreal Engine Documentation Why different colors ? Probably the same reason as normal BP nodes : to distinguish what type of node it is. You may find yourself in documentations for the meanings.

Thanks, but I can’t find the material graph nodes color description in these docs. Could you please provide a direct link to the document which describes it?

Thank you very much!
