Vantablack is a class of super-black coatings with total hemispherical reflectances (THR) below 1% [4] in the visible spectrum. The name is a portmanteau of the acronym VANTA ( vertically aligned nanotube arrays ) [ 5 ] and black .
Rich black is often regarded as a color that is "blacker than black". While this is impossible from the point of view of color theory, the difference can often be seen in the printed piece. The difference is most apparent in backlit (also known as "translite") pieces, where rich black more thoroughly blocks the light from coming through.
A hypergraph H has a vertex-set V and an edge-set E. Each edge is a subset of vertices (in a graph, each edge contains at most two vertices, but in a hypergraph, it may contain more than two). A coloring is an assignment of a color to each vertex of V. A coloring is conflict-free if at least one vertex
Overprinting refers to the process of printing one colour on top of another in reprographics.This is closely linked to the reprographic technique of 'trapping'.Another use of overprinting is to create a rich black (often regarded as a colour that is "blacker than black") by printing black over another dark colour.
Shades of black, or off-black colors, are colors that differ only slightly from pure black.These colors have a low lightness.From a photometric point of view, a color which differs slightly from black always has low relative luminance.

[1] [2] Applications of super black are in specialist optical instruments for reducing unwanted reflections. The disadvantage of this material is its low optical thickness, as it is a surface treatment. As a result, infrared light of a wavelength longer than a few micrometers penetrates through the dark layer and has much higher reflectivity.
