The sample clr you provide does not output exactly what I am looking. I am
looking for a "function" that will tweak the first enter pitch to have color
for all the <..> entries not all the pitch inside the <..> to have the same
color.

Sorry, the question 1 question is "only output (2.)" has the correct desire
output. all the others contain some undesired result. I am seeking if the
"\extractNote" can also produce the same output as (2.) in the .pdf. ie
\extractNote can extract properly for the <<{..}\\{..}>> construct note entry.
Sample (1.) and (3.) notes were not extract properly. For sample (4.) I think
this has to do with which note enter first for the <..> construct.

Do you think of sth like below?
\version "2.18.0"
clr =
#(define-music-function (parser location color music)(color? ly:music?)
(music-map
(lambda (mus)
(if (music-is-of-type? mus 'event-chord)
(let ((evt-chrd-nts (event-chord-notes mus)))
(for-each
(lambda (n)
(if (> (length evt-chrd-nts) 1)
#{ \tweak #'color #color #n #}
n))
evt-chrd-nts)
mus)
mus))
music))
myMusic =
\relative c' {
<c e g>-!
<d e f>^"xy"
<e-1>
f---2^"foo"
}
\new Staff \clr #red \myMusic
The sample clr you provide does not output exactly what I am looking. I am
looking for a "function" that will tweak the first enter pitch to have color
only (red or blue) for all the <..> entries not all the pitch inside the <..>
to have the same color.
