There is an old thread called "Madder red?" which you might find interesting....Rouge Garance had just been introduced, and in the english version of Le Monde, it was called Madder Red.....
I have a Rouge Garance Clemence Birkin which I absolutely adore! I'm a "neutral girl" so bright coloured bags ARE NOT for me, but I find this shade of red just perfect: it's a true RED, with no pink undertones like Rouge Vif (too "girly", for me) and no orange undertones like Vermillion (too bright). I don't have any pics, but I'll try and take some soon!
