My golden pothos is growing a section that is entirely white/very light green

Here is my first post on this topic: https://www.reddit.com/r/pothos/s/IIDOyCpACJ

This vine that started growing is really very light in color. The plant has its roots in my aquarium, and its leaves are directly under the lamp. I noticed that whenever there is water on the leaves, they turn brown. So I wipe them as soon as they get wet, and I put a paper towel underneath to keep them dry.

I was wondering if this is common. These are my first pothos; I have three cuttings from the same plant, and this is the only one doing this. Is it some kind of variegation? Or maybe I’m completely mistaken? For months, a new leaf of the same color has been growing. So far, there have been five leaves of the same color. They just died because I didn’t pay enough attention to the water. There have been accidents with the two leaves currently on the plant, so they also have brown spots.
