Hi Tammy,
you can do this with Custom CSS.
Each page has a slug which means a unique name.
Your work page has a class called .slug-work.
You can address your navigation on that page by doing something like this:
. slug-work .primary a {
color: red;
}
Another page will have a different slug.
Then you can customize the CSS of each page separately.
I hope I could help!
