This should always give a black background, all other objects should

\header {
  title = \markup { Rendering LilyPond files white on black }
  subtitle = \markup { for screen and projector use }
}
\markup { Any objects with unspecified colour are printed according to \typewriter page-color. }
\markup \left-column {
  \line { Here are samples of pure white along with other colours that may be easier on the eye: }
  \typewriter {
    \line \general-align #Y #-1 { \beam #5 #0 #2 "\"white\"" }
    \line \general-align #Y #-1 \with-color #"ivory" { \beam #5 #0 #2 "\"ivory\"" }

this is great! How about the attached file for an LSR snippet? Do you want to upload it yourself?
