Remove overlay banner color on some pages (Impact Template)

I am trying to remove the banner overlay color on our team bio pages, but don't want to affect the rest of the site. I have found Custom CSS code to do this with other templates, but I am not having any luck on my site. 

Does anyone know how to do this on Impact?

Add to Bio Page Settings > Advanced > Header

<style>
  .Parallax-item:first-child .Index-page-image:before {
    background-color: rgba(0,0,0,0);
}
</style>

That worked! Thank you so much!
