With #RRGGBB values printed in the *Colors* buffer it would be possible
to find closer color names even without a function, simply with a regexp
isearch like M-C-s #f.[fe].e. It will not find the closest color name,
but it is good enough to help to find all closer colors.
Even better would be if the *Colors* buffer was sorted by RGB values.
I don't suggest to do that by default, but different sorting order would
be useful, e.g. by color name, by color intensity. The latter is good
for finding a darker or brighter color than a given color, but it is not
so obvious since there are too many variants of projecting a color value
from 3-D color space into a 1-D color list. Perhaps the most useful is
sorting by hue into a rainbow, and inside every hue sorting by
value*saturation.
Great idea. There are usually so many colors in `list-colors-display' that
it is hard to find a "good" ordering - what is good for one user at one time
is different from what it is otherwise.
Being able to sort the colors in different ways would be a definite
improvement.
In terms of a default order, I do think that RGB order would be generally
more useful than color name. The current order is ad hoc, BTW - colors are
currently not sorted by name (the order is implementation-dependent, and is
essentially whatever `xw-defined-colors' returns, which is `w32-color-map'
or `x-colors').

I omitted the `#' to save more space. But OK, one character is not
too much to remind the users about the proper format.
The # is important for 1) recognition of what this is about and 2)
copy+pasting to Lisp code or to commands that ask for a color.
