The other day I was out and about my house and I accidentally stirred up some Madagascar geckos. These introduced geckos have no predators in the suburbs, so there are a ton of them. But today, one caught my eye. Usually, this gecko is a ghostly pale off-white, with many matching bumps all over its body. But this adult was a pure shade of brown on most of its body, all the bumps included, and a stripe of almost faded brown down the center of the back and the head also this color. I caught the little gecko, and it very easily lost its tail, with the absolute smallest tug of its tale, the same as all Madagascar geckos. It also acted the same as any of these geckos, not in the slightest wanting to bite, and not minding too much about humans as long as it wasn't feeling cornered. It acted as any of these geckos would, But its color were shockingly different. Does anyone know if they can mutate in an area without the animals to eat them, if t was a fluke, or any species that looks like what I described.

Well, animals mutate all the time, and most exsisting color morphs come from abberant animals found in the wild, just like you did. Even in places where they DO have predators.
That being said, I have no idea about that type of gecko.
