For this you want the Internals Reference. It's a bit indirect to get what
you want, but it goes something like this. Being first alphabetically we'll
start with the Coda symbol, but the process is the same for all of them.
In the Internals Reference there's a section labelled All layout objects -
this is where we're going to start as the coda mark is indeed a
layout object. A look down the list of the CodaMark's properties
shows there's no color property directly associated. But at the bottom of
the listing there's a number of other items listed. These are the various
interfaces that can be used. Basically each interface is a group of common
properties that are shared among various objects. And instead of constantly
recreating these properties the interface is used instead - sorta kinda in
a way a bit similar to setting up an include file with common settings.
Looking through the various interfaces we find that the grob-interface has
listed a color property. As this interface is listed as being associated
with the CodaMark layout object we should be able to make use of this
property. To put them together is simply the name of the layout object
followed by the property separated by a period. In this example we would
have CodaMark.color
Another thing to consider is what scope this applies to. For that we return
to the CodaMark page, where we see that it is created by the mark_engraver.
Different engravers live in varying contexts, and if the property doesn't
get addressed in the correct context it simply gets silently ignored. Going
to the mark_engraver page and scrolling to the bottom we see the list of
contexts where it lives by default. One of these is the Score context. This
gives us the last piece we need.
Putting all of that together we get the entry you would need to put into
your include file as (we'll go ahead and show 'em all here):
\layout {
\context {
\Score
\override CodaMark.color = #red
\override SegnoMark.color = #red
\override SectionLabel.color = #red
}
}
The Internals Reference can be a bit confusing at first, but once you get
the hang of it there's a ton of info in there. This should at least be
enough to get you started. I hope, anyway. If my explanation was muddled
somewhere just let me know - the whole using words thing to explain stuff
is a skill I'm not all that great at - and I'll try to unmuddle things as
best I can.
