I ditto what olympiceagle said. I'd kill my husband if I came home to find my home painted in a color that I didn't have a hand in choosing! So unless you know your wife really well and know that she doesn't care much about the wall color, etc., I wouldn't surprise her quite like that--especially if interior design isn't your forte. What about a "coupon" for a paint job? I didn't know how hard it was to choose a color until we finished our basement and had to choose colors.....went through $200 worth of paint samples before we found something that looked good and that we liked. Funny how a small paint chip can look so good and be the "perfect color"/what you're looking for, etc., yet once you put it on the wall, it becomes something totally different. Good luck.

I like the yellow you have, but your artwork has more blues in it. If you're keeping the rug maybe pull a blue or teal from that to inspire paint color. As for window treatments I'd do sheer light curtains, nothing too heavy since you already have heavier furniture and you don't want to take away from the beautiful molding and wainscoting.

What did you end up going with. Would like to see a room in rhinestone.

Do all the furniture pieces and carpet stay in the room? If so, take a look at Bittersweet Stem by Sherwin Williams. What don't you like about the colors you sampled?
