How to change style of IonSelectOption ionic-react

Ionic Framework
1

Hi team,

I would like to know how do I change the style of IonSelectOption. I would like to do something like this:

<IonSelect>
      {categories.map((category, i) => {
        return (
                  <IonSelectOption  key={category.id} >
                      <span style={{color: category.color}}># </span>{category.name}
                  </IonSelectOption>
                );
         })}
 </IonSelect>

This, of course, is not working, I want just the # to have a different color.

Any help would be appreciated!

Yours,
Victor
