The Sun is the star at the center of the Solar System.It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...

Graves (1902–1978), who attempted to gestate the fundamental principles of aesthetic order in visual design, [3] in his book, The Art of Color and Design (1941), defined the elements of design as line, direction, shape, size, texture ...
On Colors (Greek Περὶ χρωμάτων; Latin De Coloribus) is a treatise attributed to Aristotle [1] but sometimes ascribed to Theophrastus or Strato.The work outlines the theory that all colors (yellow, red, purple, blue, and green) are derived from mixtures of black and white.

If the reflectance spectrum of a color is 1 (100%) for all the wavelengths between A and B, and 0 for all the wavelengths of the other half of the color space, then that color is a maximum chroma color, semichrome, or full color (this is the explanation to why they were called semichromes). Thus, maximum chroma colors are a type of optimal color.
