Paint it black
I doubt that Mick Jagger will ever sing about carbon nanotubes. However NASA have devised a coating based on multiwalled carbon nanotubes that is about 10 times better at absorbing light, and thus suppressing stray light, than the black paint (NASA Z306) typically used by their instrument engineers. NASA has many observational and measurement related activities where background illumination is the ultimate resolution determinant and so require a paint that is blacker than black.
