why Ilogger.LogInformation has color in message argument?

Why the {poiId} has other color in LogInformation, and no color in my Foo?

It's one of these possibilities:

• [StringSyntax] attribute is applied, which tells IDEs to highlight and validate what can be written (but I don't see this in the code of the relevant method)
• the IDE does some magic for logging methods
• you use an extension, that does the highlighting for logging method
