Different logo on the home page

Site URL: https://bullfrog-maroon-2a9l.squarespace.com/

I have my logo in two different versions, one black and one white. The black one goes well on the rest of the website except the home page where the white one would be more appropriate because of the background image. Unfortunately Squarespace do not offer the possibility to ad different logos on different pages. 

Can anyone let me know if this is doable and how hard would be to code. I have to mention I do not have any experience coding. 

Thank you

@NicoleRothstein  The code varies depending on your version/template. If you share your website link here someone can take a look.
