They are not valid colors for the display being used.  That Emacs
goes out of its way to try to do something sensible with those color
strings is a feature meant to ease the maintenance burden on authors
of Lisp packages that use colors without defining tty-specific color
settings.

But to the user, the colors are still treated as invalid, because they
don't exist as far as the terminal is concerned.

I don't think I need an excuse: the code in tty-colors.el is designed
and written based on years of experience, and works well enough to not
deserve being called ``unfortunate'', even though it's version 1.0.

Frankly, I don't understand this outbreak of negative emotions.  I
don't think I deserve that for patiently explaining the reasons for
the current behavior and details of the internal design.  If you, or
someone else, have more questions, please ask, and I will try to
answer them as best as I can.  Then draw your own conclusions; you
don't need to accept my opinions, or to ask me to accept yours.

But I believe I do have a right to have an opinion, and to express it
without being pounced upon.  And if my opinion discourages someone
from changing the current behavior, it could be because I'm right and
they were wrong.
