You can read here a good and illustrated article: http://kpumuk.info/ruby-on-rails/colorizing-console-ruby-script-output/

I think setting console text color is pretty language-specific. Here is an example in C# from MSDN:

for (int x = 0; x < colorNames.Length; x++)
{
  Console.Write("{0,2}: ", x);
  Console.BackgroundColor = ConsoleColor.Black;
  Console.ForegroundColor = (ConsoleColor)Enum.Parse(typeof(ConsoleColor), colorNames[x]);
  Console.Write("This is foreground color {0}.", colorNames[x]);
  Console.ResetColor();
  Console.WriteLine();
}

Console.ForegroundColor is the property for setting text color.
