* Pelirrojo is the masculine form.
* Pelirroja is the feminine form.
Here are some examples of how to use it:
* "Él es pelirrojo." (He is red-haired.)

It's important to note that "rojo" by itself means "red," but it's not used to describe hair color directly. "Pelirrojo/a" is the specific term for red hair.
