I think Chanel does colour well, I absolutely love their reds, in particular my 07 Red EW bijou, my second favourite would be the delicate pink on the 05 Valentine Chain.
I rarely buy black in anything..except dress.. but for Chanel.. I think they made gorgeous bags in black...and Red, yes very pretty..love the strike red! especially in patent..so my favorite colors for Chanel is black, red and navy!
