IPhone Clock Color Will Not Change?

So I downloaded the new IOS8 on my iPhone 4s, and for the life of me I can't get my clock on my home screen to be visible. I've tried changing the wall paper, and that worked, but after I locked and unlocked the phone, it went back to a darker color and I can't see it.
