2 examples here: one units is based on Culture, other on Affinity.
Why does it matter? Every Culture spell book has one spell that works on non-culture based units, so it is always good to know what units you can produce to receive that buff.
It is small QoL update but it would make nice addition for new players, thanks for attention

Background colour.
That is even better idea tbh
And it already happens. 🙂

You might want to look at those screenshots...
Black background = Dark. Purple background = Shadow.
It is more obvious with a different pairing.
