For me bordeaux is like rouge h, a classic but of course it’s not a pop colour, so imo easier to combine with black, different shades of grey and I also feel it would work with some blue and green colours and with fauve barenia. If you have a bag you intend to use with the Bearn wallet you might take that colour into consideration. Some people carry a rainbow of slgs in their bags, so it’s a very personal decision. I like to match my bags with my slgs and only carry occasionally a wallet (mini Bearn or usually a Bearn cardcase) that pops so I can find it in my bag. I assume the hw on the wallet is phw, which would be nice with a bordeaux Carmen. The rest of the slgs could be something else. I have two agendas in ostrich, if you like exotics and find a colour you like, it could be fun to have an ostrich agenda. I would first pic the colour of the bigger piece, like agenda and go from there.
