How to change the header color only in home page?

Site URL: https://www.enthian.com/

Hello, 

I'd like to change the color of the header to black so it matches with the background picture.
But only in the home page. The other pages should remain white.  

is there any code to do this?

Thanks. 

It's transparent right now, on every page. Do you want it white on every page, and transparent on the home page?
