Sorry, that's not enough information to offer advice. The style, dimensions of the space, windows, traffic patterns, art and accessories, existing pieces of furniture, preferences? I looked at your idea books and you have some nice things saved, so good job there! Gray walls and hardwood floors USUALLY mean you could choose most any color of furniture finishes and be fine. A color scheme for the entire space could help guide you in purchasing. I doubt a gray leather sofa would be the first choice, but there are a lot of shades of gray. Do you already have pieces that will be used in the space?

Pictures would be extremely helpful. Do you have area rugs? What does the other furniture look like? Plus, there are a million shades of grey and dark floors. Really hard to say without seeing photos.

Thanks for the advice. This will be a clean slate with new furniture and decor. I'd like to use teal or dark blue accents. I even saw purple accents at the Z Gallerie, that I'd be open to.

Gray walls and dark floors come in many tones and shades. A picture of the space would be a big help.

Look at the Vapor sofa in linen at ZGallerie. Does it appeal to you?

I love white leather with dark floors but so much depends on your style and you need to share that with us .I have white leather , gray bench and I can change accent colors whenever the mood strikes

Hard without knowing exact shades and your style and the whole concept you're going for, so totally agree with others-nothing will be as helpful as seeing your pics

Without that crucial info-I can tell you so many colors your leather can be and work beautifully..whites/off whites, tan, blue, purple, green, pink..you see what's happening here? too many possibilities(and lascatx is right-generally speaking,you pay more if you want more "non-standard" color, not always but in most cases..not without exceptions though, and Macy's, with its limited choice, is indeed an exeption, somewhat. )

but many possibilities are nice to have too:)

I personally love leather in colors..and find it much more versatile to use against different backgrounds/with many pallettes, than, say, something like black.

(coming from someone who has more leather seating than she'd like to have lol..I've aubergine, off white, sunflower yellow, brick red..ready to switch some of these, at this point, frankly..I covered couple of armchairs as to have other textures, you know. they're obviously not situated in one room either..but one gets tired of leather after 20 years, even though of course it's immensely user friendly)))

please post your pics if you want more specific advice/suggestions of stores, etc

and whatever your style is-the lines is the most important thing (well and quality of course)..pleasing lines, good lines, whatever color you go for
