Who said anything about "interactive is limited to interactive
menus" anywhere?  That is where we differ and what you do not
seem to be getting.  I am talking about color.interactive that
controls the whole user experience of interacting with "add -i".

As you said earlier you may also be minority, but yes the color
pallette would help you do that.

What I am aiming at in longer term is to simplify things this way:

 * Users are categorized broadly into two groups.  The ones who
   like colours and the ones who don't want colours at all.
   color.git would control this (with backward compatibility
   options per command such as color.diff and
   color.interactive);

 * Minorities who want to disable colours for particular parts
   of the UI have enough knobs to tweak in the form of palettes.
   By definition this needs to address "particular parts", so
   "color.$command.$context" variables (e.g. color.diff.new,
   color.interactive.new; if somebody really really wants to
   have different settings between diff/show/log, that person
   could add color.{show,log}.new as well) are needed if we want
   to do this.

I think we share the ultimate goal of introducing higher level
knobs and our difference is just about minor details of how to
get there and what the intermediate levels look like.

I am trying to avoid introducing new intermediate level knobs
(e.g. color.log vs color.diff), as it is enough to disable or in
general change the way particular parts of the UI is coloured by
palette setting that specifically states which part of the UI is
tweaked (e.g. color.interactive.prompt).
