Will the GOLD iPhone 5S change COLOR Eventually?

Would the Gold iPhone 5S change to Silver eventually? From looking at it in person it seems to appear champagne colored and silver depending on how the light hits it. I was wondering if over time would it change color? (Example: Fake gold ring would change color)

I'm deciding between Gold and Silver and wouldn't wanna get Gold if it will just change to Silver eventually over using it for some time.

I'm gonna get da gold. Gimme da gold. I want da gold

No. Even if it did change silver, you wouldn't have it any other way regardless because the only other choice is silver.
