Object names for styling

[Paulo Matos]

Hi,

I am arranging some music and finding some issues with regards to
styling of objects.

For example: http://lilybin.com/ydeys1/1

How can I style the accidentals and the numbers in the TabStaff?
Initially the ledger lines looked strange not to be styled in the same
color as the note head but it might make sense as they are not part of
the note, they are part of the staff. If I wanted however to style the
ledger lines (but not the whole staff), how could I achieve this?

Thanks,
