Frankly, I think the red version truly stands out in a crowd of things. You can spot it from a mile.
In advertising, in order to validate the effectiveness of a certain design or logo, we usually throw it into a stack of things and see whether it stands out.
I have tried the same experiment with both the red and new design of the DS brochure. I must say, it is the red which stands out from a stack of things. The new brochure does not stand out in a crowd - so to speak. It blends into the whole stack because of its mild colours.
I think the new design would be more appealing if it is dropped into a personal mailbox, or a dentist lounge, doctor's clinic whereby all reading materials are all so outdated. Then it is very pleasant to see it. I guess, places like Yoga centers will also appreciate such designs. Because it is relevant to them.
Where as, in a mass public area - like train stations, the red brochure is definitely more eye catching. One can see it from afar.
I guess, if we have different brochure designs to serve different "markets" or "areas", then we will higher penetration of DS into every direction of the world.
Just my 2 cents.
