How do I change the color of my logo per page?

Hi there,

I have created a page and at the top inserted a logo. It is everywhere black for the moment, but I need it to be white on the first page, the home page. I can't find how this goes and read somewhere I needed a code? Could someone help me out, and explain me which code and also where to insert? 

Thanks a lot!
