Agreed!  I never advocated for adding rainbows anywhere.  My point is
that the "extreme cases" that need more refined colouration are not that
uncommon after all.  And I gave specific examples, such as diffs with
word-wise changes (and Magit), isearch, occur, completion UIs.

That is always an option.  My impression, however, is that we are
thinking about how to improve upon the state of affairs.  One such way
is to offer more complete face/colour coverage for everyone (and they
can still configure it afterwards).  To that I also add the
accessibility angle.  Perhaps I misunderstood the intent of this
discussion, so please accept my apologies.

These are all interesting and fecund.  A good design must avoid
exaggerations, rainbow effects, and design for its own sake.

This, however, is an indictment against poorly implemented themes,
though not extended colour palettes as such.  Your attached screenshot
uses what looks like ~14 colours.
