This one?
I think that it's a bad picture. I think that the flash is making it brighter than it really is. That said it may well be closer to red than to a true deep burgundy as this material isn't really in "fashion" anymore so it's hard to get in small quantities. So the shades can vary slightly from batch to batch.
The strap has no extra padding. This case has never come with a padded strap and it really doesn't need one being so lightweight. The 2" nylon strap sits comfortably on the shoulder.
I may at some point in the future start adding cushy straps to all the older cases but it's kind of a back burner thing right now.
I can however do any type of custom strap you want if that's all that is holding you back from ordering the case. The cost would be minimal and we can make it to match the case.
