Is my M. Auratus morphing

[damarech]

She has just started  to lose her yellow colour for more brown .
It hasn't slow her down, still chasing everybody in the tank.
Or is she only maturing.

Mine changed colors significantly.  Basically, the yellow became black and the black became yellow.  Maybe it's a gender thing.

I know that the female can become a male if it is with only females
But she is the only auratus i have in the tank
