**** fashion. You don't need white tires. Go Continental Top Contact....pricey as hell, but looks badass, will last 3-4 times longer than the tires you are currently using, never flat, role nicely, and do well in rain, gravel and offroad too. They tend to run narrow...about 3-5 mm narrower than claimed. The 700x32 is really 27mm. I imagine the 700x28 is more like 25mm. I love this tire.
If thats a little too rich for you blood or you insist on white, try a Panaracer T-serv, which I think is available in colors, including white I think, though its not pictured here. These tires roll nicely, do well in gravel, and are fairly puncture resistant, but will not last as long as the Top Contact. Still a great tire.
