Nano's syntaxes do not color everything that is valid in the relevant
language, because otherwise the regexes would also color things that
you do not want to have colored, or they would eat too much CPU time.
That's why the Python syntax requires a space before # (if # is not
at the start of the line), and the C syntax does not color multiline
strings, and other things like that.

Putting a label in the middle of a line is really poor style, so I
don't think the syntax needs to colorize it.  And a space between
label and colon... better not.  A patch to allow digits is welcome.
