How about colors and terminal graphics in std.format?

This is not exactly what you mean, but related. There are some graphics 
manipulation functions in dmc runtime: http://digitalmars.com/rtl/disp.html
These are accessible from D, but there's no header, so you'll need to 
declare them manually in your program.
Here's a translated example of outputting a red text:

//
extern( C ) void disp_open();
extern( C ) int disp_getattr();
extern( C ) void disp_setattr( int attr );
extern( C ) int disp_printf( char * format, ... );
extern( C ) void disp_close();

int main() {
int attr;

disp_open();
attr = disp_getattr();
disp_setattr(0x7C);
disp_printf( "hello world!\0".dup.ptr );
disp_setattr(attr);
disp_printf( "\r\n\0".dup.ptr );
disp_close();

return 0;
}
