As I argued in the thread that you are responding to (starting at
there's not much benefit to allowing these.

The 2-digit hex syntax saves 1 or 4 characters (depending on whether
the two digits are the same), and since the saved characters are just
repetition, it's worth even less than that.  The 1-digit hex syntax
saves 2 character, and again the savings are pure repetition.  This is
an extremely minimal benefit.

Neither of these play well with the plans to add alpha to the 3- and
6-digit hex syntaxes.

I argued in the thread that there may be sufficient value in adding a
gray() function which accepts a number or percentage, like rgb(),
because the characters savings is greater there.  As well, it can
handle alpha better, as a second parameter.
