Do all normals darken?

I know this is a random question but I've been thinking about it for a few days. Do all normals start that very bright brown and yellow and then eventually darken to the black and brown you see in most pet stores or elsewhere.

We have 2 normals, 1 a baby, and 1 full grown and they're both vividly different from one another. I just am curious if the smaller one will eventually darken out like the much larger one.

Of all of my ginetics questions, this is by far the dumbest, but I had to ask.

There is a TON of variation in normals - from bright to dark colors, clean to busy patterns, and everything in between. Generally speaking, they tend to darken as they age, but that's not a guarantee that they all will - some even do the opposite.

Just as with morphs they all can change as they age.
