How to change header style on ONE PAGE ONLY

Hi, I was wondering if you could assist me with changing the header style of my services page from dynamic to solid. 

This is the existing code in my page as I needed to add a different logo to the page:

<style>
  .header-title-logo img {
    visibility: hidden;
}
  .header-title-logo a {
    background-image: url(https://www.linkpicture.com/q/0-esign.png);
    background-size: cover;
    background-repeat: no-repeat;
}
</style>

How do I add another code so that the header is solid and the colour white?

The pic attached is what it looks like right now vs. what I want it to look like.

Thank you in advance!!

Thank you so much!
