This can be done with \on-the-fly using either \part-first-page or 
\not-part-first-page:

%%%%
\version "2.19.82"

\paper {
  oddHeaderMarkup = \markup \fontsize #12 \bold {
    \on-the-fly \not-part-first-page
      \fromproperty #'page:page-number-string
    \on-the-fly \part-first-page
      \with-color #red !
  }
  evenHeaderMarkup = ##f
}

rh = \relative c' { c4 d8 e f16 g a b c4
                  | d16 c b8 a16 g f8 e8 d c4 | }
lh = \relative c { <c e>2 <f a>8 <d f>8 <e a>4
                 | <f a>8 g <c, e> d <g b>8 <g, f'> <c e>4 }
reps = #24
ps = \new PianoStaff <<
       \new Staff { \clef treble \repeat unfold $reps \rh \bar "|." }
       \new Staff { \clef bass \repeat unfold $reps \lh \bar "|." }
     >>

\book {
  \bookpart { \score { \ps } \score { \ps } }
  \bookpart { \score { \ps } \score { \ps } }
  \bookpart { \score { \ps } \score { \ps } }
}
%%%%
