Golden Black Lyretail Mollies are two different colors?

[Hedybee]

Hello! I recently bought two Golden Black Lyretail Mollies and one looks pretty standard but the other is sort of blonde. This is my first time owning Molly fish and I was just wondering if this is normal or if there might be something wrong with him. Both fish are very friendly, lively, and happy.

Here is an image showing the blonde fish (Lewis) and the black one (Clark):

And here is just Lewis by himself:

I apologize for the picture quality.
Any ideas?

No two fish are created alike. Can't really expect all live bearers of a certain color form to look the same, much like how you can get chocolate, black and golden labs in the same litter.
