Well, they allocate an entry in the frame color_table, store the
result of ns_lisp_to_color there, and then use an index into the table
from there on. And convert it to RGBA and store it in
FRAME_BACKGROUND_PIXEL.

Donʼt do what with other face colours? As far as I can tell the same
thing is done for the foreground (and ns_lisp_to_color does look
expensive, as it parses colour names and RGB specs and probably more).
