Bridesmaid Dress Color

I actually really love this sage color and don't think they will blend too much but honestly not many people will notice if it does blend, they will be focused on you! Go with your heart

I think the shade of green you picked is fine. I'm a photographer (mostly nature) and will tell you that the photos of your venue shown are processed in a way that mutes the greens somewhat, so the natural greens will look distinct from the dusty sage color! It will be green on green, but the dusty sage will be lighter than the foliage of the trees and surrounding plants, so I think it will look ok.

Lol I chose a sage green bridesmaid color and at one point I had this same fear too, but it ended up looking great against the nature backdrop! I think you'll be fine
