Makes sense.. That particular rectangle corresponds to color 0 and
I believe it should be black.

But what doesn't make sense is that color 255 should correspond to
white or a very light grey..!

Color 255 is be the last rectangle in what is referred to as the
'Grayscale Ramp' in 256color2.pl's output.

But then, this may be irrelevant, since 'torte' is an 8/16 color scheme
anyway. Specifying color values to override torte's by anything above 15
would likely give 'unpredictable results'.

Suggestions:

What is the output of the following:

| :verbose set background
| :verbose set t_Co
| :display $TERM

Where the 'background' Vim option is concerned, it may be of interest to
see its value at startup and also after you change the default value of
the background, if done manually. See if Vim has automatically adjusted
it.

| :h 'background'

As to the value of the $TERM environment variable, where is it set -- or
do you just use gnome-terminal's default?

IIRC, gnome-terminal forcibly resets the value of $TERM to 'xterm' no
matter what you try to set it to prior to launching gnome-terminal.

Since I have no idea what is going on, you could try to to play with the
color palette in the gnome-terminal Preferences (?) dialog and see what
happens re: 256colors2.pl and in Vim with :colo torte... Might help
narrow it down..
