"The blackest black ever made on Earth..." has been created by scientists bubbling a shiny metal plate in nitric acid for a few seconds, resulting in a material that absorbs 99.9% of all visible light. I emphatically say wow to this. The new super-black will apparently have a major impact in certain fields of scientific research and industry.
And for the rest of us?
Does a color exist if there is no one to see it?
Black is a color; black is not a color: depends on who you ask. How about Frank Stella, Robert Rauschenberg, Jacqueline Humphries, Ad Reinhardt, Joseph Marioni or Pat Steir, for starters.

Black does not reflect light at any point of the visible spectrum. A response to zero stimulation of the retina, the perception of black depends on contrast with surrounding color stimuli.
Black is the achromatic color value of minimum lightness or maximum darkness,
the color of objects that absorb nearly all light of all visible wavelengths,
and one extreme of the neutral gray series, the opposite being white.

If it can be defined in light, then black is the absence of light and therefore not a color -- most especially not Super-Black. But what if defined as a pigment? Then it is a color, most especially Super-black.

It is a matter of vision and reflection, a physiological response jaded by our brain.

Super-black reflects 10 to 20 times less light than the current black standard, and is measured as being 30 times darker. So in physics, at least, a black body is a perfect absorber of light.
Still, does Super-black exist if there is no one to see it?
Please, get it in a paint can, whether I can see it or not.
