Before C# 13.0, you can use this Escape ASCII Sign 27 in .NET Console App Console.WriteLine() Just express cumbersome \u001b, \U0000001b Or \x1b, The latter is not recommended: “If you use Escapese \ X, indicate the signals following four hexadecimal digits and escape! If they are interpreted as part of Escapes. A Punjabi letter.

Usually, spent with VT100/ANSI-decape code before C# 13.0: Later:

Console.WriteLine("This is a regular text");
Console.WriteLine("\u001b(1mThis is a bold text\u001b(0m");
Console.WriteLine("\u001b(2mThis is a dimmed text\u001b(0m");
Console.WriteLine("\u001b(3mThis is an italic text\u001b(0m");
Console.WriteLine("\u001b(4mThis is an underlined text\u001b(0m");
Console.WriteLine("\u001b(5mThis is a blinking text\u001b(0m");
Console.WriteLine("\u001b(6mThis is a fast blinking text\u001b(0m");
Console.WriteLine("\u001b(7mThis is an inverted text\u001b(0m");
Console.WriteLine("\u001b(8mThis is a hidden text\u001b(0m");
Console.WriteLine("\u001b(9mThis is a crossed-out text\u001b(0m");
Console.WriteLine("\u001b(21mThis is a double-underlined text\u001b(0m");
Console.WriteLine("\u001b(38;2;255;0;0mThis is a red text\u001b(0m");
Console.WriteLine("\u001b(48;2;255;0;0mThis is a red background\u001b(0m");
Console.WriteLine("\u001b(38;2;0;0;255;48;2;255;255;0mThis is a blue text with a yellow background\u001b(0m");

Since c# 13.0 is now \e Escape sign as a brief form for ASCII 27, so that the results of the string become very compact and clear:

Console.WriteLine("This is a regular text");
Console.WriteLine("\e(1mThis is a bold text\e(0m");
Console.WriteLine("\e(2mThis is a dimmed text\e(0m");
Console.WriteLine("\e(3mThis is an italic text\e(0m");
Console.WriteLine("\e(4mThis is an underlined text\e(0m");
Console.WriteLine("\e(5mThis is a blinking text\e(0m");
Console.WriteLine("\e(6mThis is a fast blinking text\e(0m");
Console.WriteLine("\e(7mThis is an inverted text\e(0m");
Console.WriteLine("\e(8mThis is a hidden text\e(0m");
Console.WriteLine("\e(9mThis is a crossed-out text\e(0m");
Console.WriteLine("\e(21mThis is a double-underlined text\e(0m");
Console.WriteLine("\e(38;2;255;0;0mThis is a red text\e(0m");
Console.WriteLine("\e(48;2;255;0;0mThis is a red background\e(0m");
Console.WriteLine("\e(38;2;0;0;255;48;2;255;255;0mThis is a blue text with a yellow background\e(0m");
