Which Editor inspection or color scheme makes Guid operator== green-colored for C# code?

Does anyone know which Editor inspection rule, color scheme rule, or severity rule colors the `==` operator between two C# `Guid` variables to green?

For example, see this following screenshot for what I'm referring to; the full code snippet is `if(possibleValues.Exists(x => x.Uid == request.PositionUId)) { /*if-block */ }`.
