The colour Outer Space is a metaphorical representation of the colour of outer space.
Outer space, or simply space, is the expanse that exists beyond the Earth and between celestial bodies.

Outer space is not completely empty — it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
