CSS colors doesn't change on custom logo

I've used the file upload to change the main logo, then configured the server attribute to <domain>/logo.svg. It does change the logo, but that currentColor css trick doesn't seem to work now. The logo's font color is not changed when I switch from web to mobile screen. It's worth note that I have the web.override config set to a custom folder.

Any ideas?

Forget about it! I've made a mistake with the code!

Note that the currentColor won't work for a custom image. It only works for the embedded one.
