I think I've already resolved this in the patch in email "[PATCH] Make
256 color codes be based on zle_highlight array, not on termcap". The
function settextattributes() uses function from prompt.c:
set_colour_attribute(zattr atr, int fg_bg, int flags). It is there
where fg_start_code, etc. are read and set. Also, I think thath
zle_refresh.c code probably falls through to prompt.c –
output_colour(int colour, int fg_bg, int use_tc, int truecol, char
*buf), as I've had to change a condition there to not use termcap for
the 248 colors, but zle_highlight instead.

I was so pressured at this that I've done it myself :) it's in the
"[PATCH] Make 256 ..." email that contains the proposed patch.
