I am finding that in some cases (e.g. when
TERM=xterm-16color), the expression
(frame-parameter nil 'background-mode)
light when it is in fact a dark background.
How does Emacs decide the value of a frame's
background-mode at startup, and how can I affect the decision?
EDIT: I realize that I can always run
(setq frame-background-mode 'whatever), but this is not what I mean by "affect the decision" above. Rather, I mean: how can I modify the way I invoke Emacs (including the shell environment in which I invoke it) so that its default algorithm for setting
frame-background-mode at startup gets it right.
EDIT2: I do not see how the answers to Emacs Blue color too dark answer my post's main question, namely: how does Emacs figure out the value it should set
frame-background-mode to at startup? (For the sake of this question, assume that there is no
.emacs/initialization file at startup.)
