Change desktop's directory color

As you can see in the picture below, there's something weird with my Desktop's folders.

When being inside the File's tool, the directories are painted with their colors.

As you can see in the Desktop's ones, this does not occur.

I wonder if there's a way to solve that.

Thanks in advance !!

The icons on the desktop are currently provided by a Gnome Shell extension "Desktop Icons", or "Desktop Icons NG" on Ubuntu 21.10, not by the file manager Nautilus. These desktop extensions are more limited in functionality. In particular with the "Desktop Icons" extensions, desktop icons cannot be customized.

If you use "Desktop Icons" (default in 20.04), you may want to move over to "Desktop Icons NG". It has a lot more functionality, but I am not sure whether that extension effectively does support supports customizing desktop icons.
