When you print tabs using Console.WriteLine, they never use the specified background color:

Console.BackgroundColor = ConsoleColor.Red;
Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine("No tabs, no spaces");
Console.WriteLine("\tTabs don't have background color");
Console.WriteLine("    Spaces have background color");

Did I miss something or is it by design?

CodePudding user response：

After some testing it looks like this is related to how the native Visual Studio debugger renders the output and is not by fault of your code or app.

e.g. See below a side by side running a sample through the debugger vs directly through command line.
