I haven't done anything to specify Lynx colors at all.  lynx.cfg is
right out of the Lynx distribution (to my surprise it does have one
color setting, "COLOR:6:brightred:black").  I also checked the compile
options via "LYNXCOMPILEOPTS:"; all mentions of "color" are:

  color_curses                        'yes'
  func_assume_default_colors          'no'
  func_use_default_colors             'no'
  COLOR_CURSES                        1

Have you tried to duplicate this with ncurses or anything else
(Solaris?), using terminfo entries that offer >8 pairs (either naturally
or by modifying the terminfo entries)?

If it's a bug in the curses library, I'm in a position to fix it, except
I don't understand curses internals that well.  I need help
understanding what sort of mistake it could be making that would lead to
this problem.
