Further to this it seems the effect of this tweak is rather odd. The color of
the following note head is changed but the note stem
is also thinner and this effect carries over to the next notes and indeed the
number of notes affected varies see
\version "2.19.15"
\displayMusic
\relative {
c'4 c4 c4 c4
\tweak color #red c''4 c4 c4 c4
}
The plot thickens.....
