I have had a different experience ......
I prefer the color 8 that has more purple overtones ( for some reason, the various color 8 models I have from BB are all wonderful in this regard). But I like all shades of 8.
In my experience, however, it is the lighter shades of color 8 that have more of a tendency to appear/turn brownish. And AE's burgundy shell - which almost always has brown overtones - is nearly always (perhaps always) lighter that Alden's color 8. All of my AE burgundy shells are lighter.
Also, I have owned/ordered two Alden color 8 LWBs and they were both considerably lighter than my other color 8 models. The last color 8 LWB I ordered was returned - one of the reasons being that the shade of color 8 was too light for my liking.
Don't get me wrong, I still love my eggplant shade of color 8. I've gotten a bunch of complements for my "ox blood-looking" PTBs. All I meant was that I prefer the darker look of my LWBs. I've come across a few pairs of AE MacNeils that have a tremendous shade of dark brown shell with a hint of burgundy. Unfortunately I have not found a MacNeil that feels remotely as comfortable in fit as my 975. I suppose the 7-97 last just wasn't designed for my foot. I've seen that same shade in a few Leeds but just not in my size. I'd be happy with those also.
