Bordeaux! It's so pretty in Clemence and very versatile in the way that Rouge H, Prune, raisin, and oxblood colors can be. Etoupe will always be available. Etoupe works wonderfully on some people...I find it looks muddy on me.
I have an Etoupe Evie and it goes with everything! If you think you'll only have one, go for Etoupe. Bordeaux is pretty but as others have said, for me it's a fall/winter color. That said, if Bordeaux makes your heart sing, go for it! Etoupe is always available and Bordeaux will go away at some point.
