Description
For a custom theme, I'd like to change the default point color away from black.
I can hack this for all coming ggplots by changing the geom_point default_aes,
but I'd like to have a per plot API for this.
Any suggestions how we'd implement this?
Perhaps we can get away with not having an API but using the first scale_color entry,
just like we'd do if there was a mapping?
(Right now the scale_color complains about not being used).
My theme set's color and fill scales anyhow.

Research direction
Start by reviewing how custom themes set geom_point default_aes and how the first scale_color entry is handled when no mapping exists. Clarify whether the goal is a per-plot API or automatic use of the first color scale, then define the expected behavior for unused scales before identifying implementation and test locations.
