Can't adjust form lightbox button hover color and lightbox form colors

Hi there,

https://www.peoplethebrand.com/b2b-saas-homepage-headline-formulas

Page code: 42224

I'm trying to change the lightbox button hover color on a page I'm creating, but nothing seems to work. I can't figure out which site-wide palatte controls to adjust to fix this.

The button is white with black text when static, but when I hover, the text goes white, which leads to white-on-white display (see image).

Ideally it would go black with white text on hover. I'd also okay with there being *no* hover effect if that's the best fix. 

Same with the actual form that appears when clicking - it's mostly pink and black (see image). But again, can't figure out which site-wide palette controls to change to get desired result. 

Perhaps this needs code injection? Appreciate any help someone can provide! 

Thank you!

@Ashley_Peoplethebrand I have CSS code solution for this. Below is the code you need to add into CSS editor

.lightbox-handle {
  &:hover {
    color: #000 !important;
  }
}
.lightbox-content {
  background: #ff3cc7 !important;
  .form-button-wrapper .form-submit-button {
    &:hover {
      color: #fff !important;
    }
  }
}
