Martha Stewart's Plumage is a similar color.

No, Plumage is too teal, this color is greyer, warmer. I've love to know what it is!

Thought it might be Benjamin MooreTimber Wolf....but I'm thinking its something with much more violet in it... great color though!
Just took a peak at the BM site...I think it's Flower Box - http://www.benjaminmoore.com/en-us/for-your-home/color-gallery?cd=CSP-530&col=CSP

I'm inclined to agree!

BM philipsburg blue

Whatever the colour is, it is NOT Plumage. There is not enough green in the paint of the accent wall. Even if my monitor is slightly off-the undertone is way off to be Plumage

I think it is Sherwin Williams , Refuge

I'm rethinking ... I think it could be Benjamin Moore color stories "Andes summit". I just painted my dining room that color and it seems to be very similar

SW Revel Blue...very similar...violet undertones

Looks a lot like Benjamin Moore, Black Pepper. Love that color!

Anyone know the make of this sofa or something similar, please?

The blue sort of looks like "bracing blue" by Benjamin Moore
