How do I chnage the font colour on header (Homepage ONLY)

I recently changed my homepage image.

Now the page title text colour is not visible.

Is it possible to have a single block/strip  of black along the top of the page, and the font in white, so that the logo and page titles stand out?

 Thanks

@Immortal_Explorer looks like you've sorted this one - did you still need help?

No I've sorted it.

Thanks anyway
