Changing mobile logo on different pages

Site URL: https://christinalister.co.uk/

Hi there! 

I have some custom code in my header injection to change my logo from white to colour, on two pages only. However, can I carry this forward to mobile? Is there any specific code for that?

Thanks!

With mobile, wrap your code in media query

@media screen and (max-width:767px) {
paste your code here.
}
