I haven’t seen the dark tan in person, but I have the camel and it’s definitely a much lighter, warm golden brown and the dark tan looks to be more reddish/ dark brown. The photos online of the camel color are very deceiving IMO - it looks way darker than it actually is. But I think it’s now sold out everywhere unfortunately. I attached a photo of mine for reference. I love the cloud blue color (I originally bought the saddle in that color but ended up returning it for the Bobby) and I thought long and hard about that color but in the end just thought camel would go with more of my wardrobe / I’d be more likely to wear it super long term. However I do think if I had to choose between the dark tan and the cloud blue personally I’d go with cloud blue - I don’t love darker browns as much for some reason, and I love grey-hued blues, they’re my absolute favorite shades.
To the earlier poster, the narrow opening does bother me occasionally, but not enough to turn me off from the bag completely. It’s like a very slight minor annoyance, but agree it’s at least noticeable.
