if you mean can you change the front screen bezel/surround to the screen from black to white then the answer is yes. Would I do it? Dear me no just in case I screwed up.
There are many companies that can do it for you though if you don't fancy going down the DIY route. If you do fancy doing it DIY, the YouTube video link below might be helpful
Screens are available from eBay for not much money at all and it would appear from a Google search that the front screens on the 5S and 5C are interchangeable (although don't quote me on that). You might want to do some research on that though, just to be sure.
