This is something you should be thinking carefully about! It’s a lot of money to spend. H makes so many colors that could pass as neutral. Wonderful blues, dark reds, many shades of gray and beige. I recommend doing your research on here and on H.com to get a better idea of the colors offered. It is by no means a binary choice between black and graphite. I also wouldn’t make a decision based on how difficult a color is to find or how rare it is. I would base it on what color speaks to you and works best with your wardrobe and existing collection.
Yes, you're right, it is a lot of money! That's why I thought black or grey is a save choice and both colors speak to me. I love looking at all the blues (I did a lot of research for the color), but I reach for my blue LV the least. That makes me avoiding a blue one for such an expensive bag. I always wanted a red, but I'm not sure how often I would reach for it. I can imagine that I want a bright pink in the future as a second one, but not in the near future. Sorry for my indecisiveness and thank you very much for your helpful input!
