winapi - C++ Win32 Console Color

I know a bit how to do colors in Win32 C++ console. But it's not really efficient. For example:

 SYSTEM("color 01")

Slows down a lot on your process. Also:

 HANDLE h = GetStdHandle ( STD_OUTPUT_HANDLE );
 WORD wOldColorAttrs;
 CONSOLE_SCREEN_BUFFER_INFO csbiInfo;

 /*
  * First save the current color information
  */

 GetConsoleScreenBufferInfo(h, &csbiInfo);
 wOldColorAttrs = csbiInfo.wAttributes;

 /*
  * Set the new color information
  */

 SetConsoleTextAttribute ( h, FOREGROUND_RED );

Works great, but it doesn't have much colors. Also, FOREGROUND_RED is dark-red.

So what I want to ask, isn't there a way like CLR property Console::ForegroundColor set, so you can use any color from the ConsoleColor enum?

The console only supports 16 colors, which are created by combining the four values as follows (I might have got the gray/darkgray confused, but you get the idea):

namespace ConsoleForeground
{
  enum {
    BLACK             = 0,
    DARKBLUE          = FOREGROUND_BLUE,
    DARKGREEN         = FOREGROUND_GREEN,
    DARKCYAN          = FOREGROUND_GREEN | FOREGROUND_BLUE,
    DARKRED           = FOREGROUND_RED,
    DARKMAGENTA       = FOREGROUND_RED | FOREGROUND_BLUE,
    DARKYELLOW        = FOREGROUND_RED | FOREGROUND_GREEN,
    DARKGRAY          = FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE,
    GRAY              = FOREGROUND_INTENSITY,
    BLUE              = FOREGROUND_INTENSITY | FOREGROUND_BLUE,
    GREEN             = FOREGROUND_INTENSITY | FOREGROUND_GREEN,
    CYAN              = FOREGROUND_INTENSITY | FOREGROUND_GREEN | FOREGROUND_BLUE,
    RED               = FOREGROUND_INTENSITY | FOREGROUND_RED,
    MAGENTA           = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_BLUE,
    YELLOW            = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_GREEN,
    WHITE             = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE,
  };
}
