My experience with having colors represented online accurately has mostly been good. Always hesitant when swatches arent available. Pistachio was not in any review photos, which can often give some idea. 

I like this color fine, but even allowing for photography lighting v. my inside artificial  lighting, the fabric is not as vibrant a green. Im OK with the piece and its other attributes but but just be aware that Pistachio isnt as vivid as shown.
