Couch is definitely a teal blue,  turquoise blue, Blue, Couch. And its own right it is beautiful, However  it is not emerald green, 
A remotely any color favoring any kind of green. So if a green couch as what you are in store for do not buy this brand. I really wish that they would update this color on their website to teal or turquoise because it is not even remotely in the green color wheel so it’s very misleading and very disappointing when you get it unboxed and realize that it is not going to work with your other green sofa and then you have to figure out what you’re going to do at that point. The sofa totally misses the mark and the color but is definitely pretty for a turquoise teal blue so keep that in mind
