Here's an example of the Home Feed:
And an example of the Global Feed:
This is pretty easy to do if you're using Firefox and a user content stylesheet. But you could also use the Stylus Add-On to do it. There is also a Stylus Extension for Chrome (and other Chromium-based browsers).
For Safari there is the Userscripts Extension in the App Store, which can also do user stylesheets.
Friendica needs Settings > Display > Theme set to the "Frio" theme.
Under Settings > Display > Theme Customization it needs to either be set to "Lite" or to "Custom" ("Dark" nor "Black" will not work).
If you set it to "Custom" you need to "Save" it first to see the options. Then you can copy+paste my "schemestring" into the box and "Save" again. Even if you don't apply the user styles that will get you a newer FB color scheme.
I haven't looked at any of the documentation for Friendica themes. I have no idea if my stylesheet could be adapted to a "Frio" variant/scheme. If anyone else who knows more about it wants to try feel free to do so. But even if it can the server admin would still have to make it an option. This way you can apply it yourself.
I'll try to add links to the stylesheet files in the comments, though this is my first time using Friendica's file attachment features.
