The dark blotch on the front half of her dorsal fin gives it away. Plus the lack of spangles all over the body.

Here is a male I had for a bit. See how it looks like each scale has its own spangle

Agree its a female.
Here are a couple females I had.

Now a male (below)

Note the lack of melanin in the dorsal, but also notice the array of iridescent spots it does have on the fins and body, lacking on the females.

Anzo, it is a little difficult on yours, because there are typically male spots on the dorsal, and the dark area usually on females
But below, a femaleI had that had some spotting on the dorsal (a lot may depend on if there is a male in the tank), below at the time of the pic, no male was in the tank.

After a male was added, she turned to this below

Thank you for the explanation it helped very much
 
One of the things I find really interesting about cichlids, is their chameleon-like ability to adapt to situations.
Festae are not the only "heroine" cichlids that change drastically when a male is not around, not only in color, but even in body shape.
Below is a female Nandopsis haitiensus in normal color.

When I removed the male from her tank temporarily, her color and body shape became more male like, below

another example is Australoheros "red Ceibal" from S America.
