Change Title Font Color on specific pages

[JuliaRiv]

I need to change the font color of my title for my about, purchase option, artwork movie, and pitre's life story page's.

They need to be changed from white to black. I only want those specific titles to be changed.

The goal is for those titles to be blended into the black background and be invisible to the viewer.
