Best backsplash for busy granite countertops.
I think with a really busy granite you should go with a simple backsplash.
Third get a remnant piece of your granite and go for a 2 bs and paint the wall above that.
Some busy granite countertop backsplash ideas below are granite countertops and countertops glass travertine marble grey granite from tile backsplash and quartz countertops with this lemurian blue pack.
From various forms of tile.
As mentioned above you will have many options in terms of materials for your backsplash.
With your dark cabinets i believe that a cream or ivory whichever is closest to the light color in your granite in a subway tile would look really nice.
I love the glass moda tile from julian tile.
First choose a white tile that matches the white of your cabinets.
One thing i always tell my clients is you can never go wrong with subway tile either ceramic or glass or marble depending on the granite.
If you decide to go with a granite countertop make it the star of your kitchen and choose the right backsplash.
If you found a granite countertop that takes your breath away one option for a backsplash is to use more of that same stone.
Or if you really want glass the honey colored subway would look good.
Second choose a light background color from your stone as the above recommend.
