Hi David,

This looks pretty amazing so far — thanks for the great work!

When I try to apply it to a score with edition-engraver tweaks, it doesn’t seem to colour anything tweaked using the EE.
It does seem to colour things tweaked otherwise (e.g., in the “content”).

Maybe I’m doing something wrong? I’m simply using

    \colorOverride \theScore

Could you clarify how you are defining \theScore here?  Are you defining the score with \new Score { [...] } minus a layout block?  I bring this up because I can't see how errors wouldn't arise if you do it any other way.

More details:

If you do the following--

theScore =

\score {

[...]

}

You can get the score appear with

\theScore

or

\theScore \layout { }

However, you can't apply the music function \colorOverride to \theScore:

\colorOverride \theScore

returns the error

wrong type for argument 1.  Expecting music, found #<Score>

\colorOverride 

               \myScore

Of course, if you put \colorOverride within the score somewhere like:

theScore =

\score {

  \colorOverride

  \new Staff {

    c'

  }

}

all is well.

However, you can do

theScore =

\new Score {

[...]

}

and

\colorOverride \theScore

will work fine, because \theScore is a music _expression_

%%

Does this logic apply to what you're doing, or is there another way?

Best,

David
