This is easier than one might think, but - somewhat counterintuitively -
you need _two_ instances of the word \with.

\version "2.23.7"

rainbowSettings = \with {
   \override Clef.color = #red
   \override TimeSignature.color = #green
   \override StaffSymbol.color = #blue
   clefGlyph = "clefs.C"
}

\new Staff \with \rainbowSettings {
   \key d \major
   d'4
}

\new Staff \with {
   \rainbowSettings
   \magnifyStaff 2
} {
   \key d \major
   d'4
}

And I just found out that you can even do

rainbowSettings = {
   \override Clef.color = #red
   \override TimeSignature.color = #green
   \override StaffSymbol.color = #blue
   \set clefGlyph = "clefs.C"
}

(To wit, if rainbowSettings are entered as music instead of as a \with
clause, context properties have to be set with \set.)
