Many who polled have probably never seen the colours you are asking about in the flesh. I would trust your own eyes and intuition rather than depend on this poll.
I agree it is very helpful to see the colors in person. I had a briefcase made by SAB and they sent me leather swatches. The chestnus swatch I got has a strong orange tint. The dark london tan has no orange but is rather light. Neither looked like the briefcase at the start of this thread. If I had to choose between swatches I would have gone with dark London tan. In the end I had the briefcase made of dark brown (Havana) and was very happy with the choice. I suspect both the dark London tan and chestnut would develop a nice patine with time but it takes years and years!
