Coloration in fermenter

Does anyone know why there's a darker layer on top? Pictures attached

It's clearing. Fermentation is winding down or complete and your yeast is beginning to settle. It clears from top to bottom, so that dark area on top should steadily get larger as the yeast drops more.

Yep, gravity

Did you use a yeast starter?

I get that type of situation early in my beers when I use a yeast starter. I don't ever worry about it.
