What are primary colors? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? What are primary colors? If you pass a sunbeam through a glass prism, you will see that it turns into a rainbow of colors called a spectrum. It consists of all those colors that together form the so-called white light. But while you can probably see six or seven colors, white light is actually made up of three primary colors. These colors are called primaries because they cannot be combined with other colors. The primary colors are orange-red, green and violet-blue. The other colors you see in the rainbow of the spectrum are combinations of primary colors. Looking at the spectrum, even with the naked eye, you can easily see three mixed colors, which are called secondary: blue-green, yellow and red. You can get these colors by mixing primary colors in certain combinations. But remember that we are talking about light. Paints for drawing are solids, that is, the exact opposite of light colors. Secondary light colors are the primary colors of paints. This means that among the colors, the primary colors are yellow, green-blue and red. By mixing these colors, you can get all the others. There are many other ways to classify paints. Bright colors obtained without the help of black or white inks are called pure colors. Yellow, red, blue and green are pure colors. The colors obtained by mixing pure colors with black are called colored shadows. Dark brown is a color shade. Colors obtained by mixing them with white are called hues. Pink color, ivory color are shades. Colors obtained by mixing pure colors with black and white are called tones. Reddish brown, beige and gray are tones. Here is another interesting fact about color. What color do you think the red paint is before you open the box? She doesn't look red, but black! This is because where there is no light, there is no color. In a dark room, there is no such thing as color. The color of an object depends on the material from which it is made and on the light in which we consider this object: for example, a red-orange sweater looks like this because wool dye reflects the red-orange part of the light spectrum. Violet-blue and green parts of the spectrum are absorbed by the material of the sweater. Only orange-red rays are reflected, which is what you see. Author: Likum A. Random interesting fact from the Great Encyclopedia: Where were gas lamps installed at the end of the 19th century where you could buy hot coffee? In 1897, Pluto Lamp gas lamps were installed at several points in London. These devices were not only street lighting, but also worked as vending machines, offering hot coffee, tea and cocoa. In addition, cigarettes and postcards could be bought from vending machines. One of the models even had a telegraph connected to send messages to Scotland Yard - and it all ran on gas.
