I think you should be able to use long instead of Int64. It's the same type. Int64 is not color syntaxed because it's the actual type, while long is the alias. Same different with int/Int32, short/Int16, string/String, etc. This is all depending on your color scheme. I have a wacky one, so Int64 is blue (because it's a struct) and long is orange (alias). String is yellow (class).
