A novel material of this color is made of vertically aligned nanotubes and is known as "vanta"-​this color.
A novel material of this color is made of vertically aligned nanotubes and is known as "vanta"-​this color. Every path from a node to its leaves has the same number of nodes of ​this color in a type of tree named for it and an alphabetically-​later color. This color names an object that emits radiative power proportional to the fourth power of (*) ​temperature, according to the StefanÂ–Boltzmann law. This type of "body" absorbs incident radiation of all frequencies. In computer science, a device whose internal workings are unknown is called a "box" of this color. For 10 points, identify this color corresponding to the absence of light.
