What would the SF do?
I got these oxblood from the CEO sale. Seems really close to me to my existing burnished dark chili. Side by side there's a difference, but not sure there's really a practical difference. (I've got a walnut and black AE already.). Thinking of returning and saving the $300 for another day. Side admittedly looks more unique than tops.
They don't look similar to me really. In fact your DkC looks much more brown than what I have, but that is probably due to them being side by side with a much redder tone. In terms of you wanting to invest in more diversity then that is a personal preference. If you won't wear them then no ones opinion matters. For what it's worth the ox looks well done.
