I (think) I love this color, but the pictures I find vary quite a bit. It could be the lighting, but different pictures seem to show this differently. Sometimes it leans more neutral gray, sometimes more sage-y and warm, sometimes more blue-gray? It seems the closest paint match from other manufacturers is Behr Urban Nature and Ben Moore Ananthus Green. Also based on https://encycolorpedia.com/b9beaa, F&B's Pigeon consists of more Green and Red than Blue.
Obviously, we'll have to have some samples made up to look at it in our space, but wondered if anyone had any pictures they'd be willing to share from their spaces? :-)
