Backsplash to warm up white-ish cabs & granite
I have been stumped by the backsplash for far too long now. Have looked at so many pictures and read so many of your enlightening posts, but I think the best strategy now is just to ask. Our cabinets are espresso on island and one side of kitchen and an off-white glazed color on a large section of the perimeter (pictures below). The backsplash will go where all the white-ish cabinets are. We love the granite -- mostly white with grays, taupes, and bits of garnet. It looks gorgeous on the dark cabinets but needs some warmth near the lighter cabinets so it does not look so washed out. Am hoping the backsplash can help without overpowering or contrasting too much.
General plan was to have a mosaic (glass -- maybe Sonoma Tantrum) above stove and keep all else simple. Field tiles I've considered either blends in too much with the granite (eg, the light olive green limestone I wanted to use originally) or competes too much (eg, most slates seem too rustic and busy). Seems like a creamy or beige tumbled stone would be too plain, but would their smoothness and uniformity in color make the granite pop more? And, actually, tumbled or glazed ceramic? (I like Ann Sacks and WZ type tiles and what many of you have done with them, but would that be too cold here?) Though I love color (dining room next to kitchen is chocolate brown), I think a really dark or bold backsplash would contrast too much for us here (but I like the warmth of the copper plate above hood! BTW, we can paint that area above hood a different color).
Am striving for an elegant, simple, warm look for the kitchen. Am totally confused! Any advice on color or material? TIA!
