CSS is definitely where images are specified. See https://docs.gtk.org/gtk3/css-overview.html#:~:text=CSS%20nodes,each%20node%.... As well as how to specify images, how to specify states, eg active tab, that has an example of changing a notebook tab colour. You would need an alternative image, so maybe changing the colour will be sufficient if you make your active tab bright orange so it stands out ;-)
I'm not about to learn CSS/GTK, that would take the rest of my life. Nope, if someone can point to the exact place to make the change then I'd pursue the issue but otherwise it's not worth the time. Thanks anyway Lex.
