Faint grey, like the trail of a particle that's passed through, leaving no mark.
Cosmic Ray is a pale grey.
It can be described as pale, delicate, faded and almost grey.
Set in black, because black reads best on it.
Cosmic rays or astroparticles are high-energy particles or clusters of particles that move through space at nearly the speed of light. They originate from outside the Solar System—from the Milky Way, from distant galaxies, and from the Sun. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk are deflected into space by Earth's magnetic field or by the heliosphere.

With both found footage and original material, it features images of countdown leader, a nude woman dancing, a Mickey Mouse cartoon, and military exercises. It is soundtracked by a performance of Ray Charles's "What'd I Say" and has been recognized by some critics as one of the first music videos.
