Beautiful color palette! It would lead me to go quiet with the upholstery fabric (off white, barely there blue, wispy gray, etc.) for the chairs and introduce texture, rather than color, for accents. Natural wood, boucle wool, tweed, stone, frothy pillows and maybe a dash of beach glass!
I've loved this lamp for ages and can totally see it fitting in with the colors and subject matter of your inspiration photo. I also like that the stacking nods to the stacked stone of your fireplace. (Totally off topic, I know, but got excited when I saw your photo and had to share!)
