Etymology
The compound adjective "red-blue" is a modern English formation, directly combining two primary color terms of ancient lineage. "Red" descends from the Proto-Germanic raudaz, ultimately from the Proto-Indo-European root h₁rewdʰ-, meaning "red" or "ruddy," which also gives rise to words like "rust" and "ruby." "Blue" traces back to Proto-Germanic blēwaz, though its earlier PIE ancestry is less certain, possibly linked to a root meaning "light-colored" or "yellow." The compound's logic is transparent, denoting the simple combination of these two hues. Its extended political sense is a 21st-century American metonymy, deriving from the established color-coding of the two major U.S. political parties on electoral maps.
