Hi Emacs developers,
The following 'face' is extracted from 'dictem.el¹'
(defface dictem-database-description-face
'((((background light)) (:bold t :foreground "darkblue"))
(((background dark)) (:bold t :foreground "white")))
"The face that is used for displaying a database description"
:group 'dictem-faces)
In X, start 'emacs -q -l dictem.el':
dictem-database-description-face is initialized to:
......
Weight: bold
Slant: unspecified
Foreground: darkblue
......
In Xterm, start 'emacs -nw -q -l dictem.el':
......
Weight: bold
Slant: unspecified
Foreground: white
......
*NB*: emacs has a light background in both x and xterm. Thus it looks
very weird the aforementioned face is initialized to the dark
background value.
Tested in GNU Emacs 23.0.0.6 (i686-pc-linux-gnu, X toolkit) of
2007-05-31.

Emacs cannot determine the background color on a text terminal, so it
assumes something. Without -nw, Emacs queries the window system about
the default color, so it can adjust its background mode.
Try setting frame-background-mode to 'light in the xterm case, and I
think you will have the colors that you want.

I understand this.
But all other faces are correctly set for example, those in org.el. If I
set the spec to:
(defface dictem-database-description-face
'((((background light)) (:weight bold :foreground "darkblue"))
(((background dark)) (:weight bold :foreground "white")))
"The face that is used for displaying a database description"
:group 'dictem-faces)
It will initialize correctly in both xterm and X.
Seems there is a bug in Emacs.

Interesting. I use dictem.el on both X and xterm and don't have the
reported problem. On xterm, Emacs correctly determines the background
color of this face.
On closer investigation, I discovered that Emacs doesn't determine
the background mode only when dictem.el is loaded from the command line
with `-nw -l dictem.el', as Leo did according to his report.
Really, when started only with `-nw' and without `-l dictem.el',
and later loading dictem.el with (load "dictem.el"),
default-frame-background-mode is 'light.
But
emacs --batch --eval '(message "mode: %s" default-frame-background-mode)'
prints
mode: nil

The background mode is only initialized in non-batch mode (in
normal-top-level or in the terminal init file).

It doesn't determine the background mode even in non-batch mode:
emacs -q -nw --eval '(message "mode: %s" default-frame-background-mode)'
displays in the echo area just after start on the text terminal:
mode: nil
whereas evaluating it in Emacs displays:
mode: light

command-line is called first.

There are altogether 5 faces defined in dictem.el.
With "emacs -nw -q -l dictem.el" in xterm, two of them initialize to
light background values and three of them to dark background values:
.----------------------------------+-------.
| dictem-reference-definition-face | light |
|----------------------------------+-------|
| dictem-reference-m1-face | light |
|----------------------------------+-------|
| dictem-reference-m2-face | dark |
|----------------------------------+-------|
| dictem-reference-dbname-face | dark |
|----------------------------------+-------|
| dictem-database-description-face | dark |
`----------------------------------+-------'
Whatever emacs assumes for its background mode, something is wrong. I
hope someone can see this problem and fix it.
regards,

This seems to work properly on the multi-tty branch. That branch has
a few changes for initializing faces on different frames. If nobody
looks at this issue now, it will hopefully be fixed when the multi-tty
branch is merged.

I think this issue might have been fixed for a patch that normalizes
face definition, which was installed sometime ago.
FWIW,
