Gorgeous rooms/colors! Personally, I would move the 'blue' paintings to the walls with the Silver drop gray colors. I think the contrast would make the room, and the arts, pop! Also, as someone mentioned above you can def. frame canvas (I'm an artist and do so regularly), and actually you can go to Michael's and pick up frames that would fit a canvas (without having to special order them). :))

So interesting to think about the implications of lighting - I will definitely have to play around with different bulbs! Gracie01, the art is actually a 4 piece panel (antique, Chinese, gold w multicolor cherry blossoms, birds, etc) I agree that's not showing as such on the monitor. Pillows are gold in same fabric as chair on opposite wall. Second set of pillows has a creamy background with green-ish geometric pattern - again, absolutely agree it's not appearing that way at all through these pics. I'm realizing that part of my issue is that I never really wanted yellow walls to begin with, and sort of let the painter (whom I actually think is great) influence the decision to do this Greenmount Silk. I'd actually prefer something like a BM Gray Mirage at 50% or so...as it is, the blue against the yellow still looks garish to me. I don't want to change the window treatments, unfortunately, as they were custom made for this space, and price-y. I really appreciate all of the helpful suggestions!

Large open entrance, living room and dining room

A shade of blue would have been my suggestion too. I see blue in your pillows, not green. I agree a rug, with a pattern on it (possibly some shades of blue in it), that is larger than what you have would look very nice. I like the blue on the walls in Celerys picture.
