Some interesting information about black and white colors:
Black is the darkest color, the result of the absence of or complete absorption of light. It is the opposite of white (the combined spectrum of color or light). It is one of the four primary colors in the CMYK color model, along with cyan, yellow, and magenta, used in color printing to produce all the other colors.
Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century.
In particular, the black color can be obtained by subtractive blending scheme with yellow, magenta and cyan dyes. For the production of soluble ink is often a mixture of green and red dyes.
White is an achromatic color, literally a "color without color", composed of a mixture of all frequencies of the light of the visible spectrum. It is one of the most common colors in nature, the color of sunlight, snow, milk, chalk, limestone and other common minerals. In many cultures white represents or signifies purity, innocence, and light, and is the symbolic opposite of black, or darkness. According to surveys in Europe and the United States, white is the color most often associated with perfection, the good, honesty, cleanliness, the beginning, the new, neutrality, and exactitude.
Additive color synthesis, due to the human visual feature of the device, allows to obtain a white color by mixing red, green and blue spectral colors, applied, for example, in kinescopes.
