Color perception is very individual and depends on how the human eye perceives the rays reflected from different surfaces.Any surfaces that do not reflect the rays and absorb them.When a person sees their absorption black.That is why black is called "dead" color or "lack of color."
Therefore, the answer to the question of how to get the black color of the paint will be the following: a true black can not be obtained by mixing any other colors of the spectrum.However, you can create a very dark shades which in contrast to the other creates a sense of black.To find out what colors to mix to get a black color, is to turn to art theory and psychology of color.
Color models and color synthesis
There are two models of synthesis of color, that is, to obtain new colors and shades.
additive - get the color model, based on the addition and superposition of rays reflected from the surface of objects.This model is used in monitors and screens, its main color gamut RGB.Additive color synthesis uses basically three main light: red, green and blue.By superimposing and mixing these rays are formed all the other colors, other than black.In this model, the black color is considered to be the complete absence of reflection.
Subtractive - a model based on a mixture of natural pigments and dyes.It is considered to be a lack of color white.And black is prepared by mixing all basic colors.So what you need to mix paints to get a black color?The subtractive model of primary (or basic) are shades of magenta, cyan and yellow.
Subtractive method of mixing
compared with additive synthesis subtractive color model produces fewer shades.Furthermore, a theoretical or mathematical model subtractive fundamentally different from that obtained in practice.For example, theoretically stirring three primary colors should turn black.In practice, however, this color goes very dark brown.
subtractive method is used in the printing and graphic arts, where it is very important to achieve this in black.In order to get it to the three primary colors add a "key."This is where the name of the main range of the subtractive model - CMYK, where C - cyan (cyan, in Russian it is called blue or greenish-blue), M - magenta (a shade of purple), Y - yellow (yellow), and K - key colour(key color).In this range, the key is a natural black.Wondering how to get a black color from the chromatic colors of the spectrum, typographers realized that none of the resulting shade will not replace natural black.
three primary colors
According to the theory of art of Johannes Itten, there are three primary colors, which are obtained by mixing all the other colors of the spectrum.Itten highlighted in red, yellow and blue as the main.Subsequent theories have determined that the ideal primary colors are purple (magenta), blue (cyan) and yellow.That they are called primary - colors which reflect the greater range and which can not be obtained with a combination of other colors.
In fact, red and blue are not primary.They absorb more light than reflect, but despite this, they are still often referred to as primary colors and are used to create the rest of the color wheel.
Note: White and black are not included in the spectrum and color wheel are called achromatic.The way to get the black color of the paint is always different and depended on a variety of currently existing theories.
pure color
In early theory of pure colors were red, blue, yellow and green.It was believed that they could not get by mixing other colors.Later, with the development of technology, it was found that the three primary colors that can not be obtained - a purple, blue and yellow.
modern theory distinguishes three primary colors, three secondary chromatic and achromatic one - black.So, what colors to mix to get a black color, different.Compared operates everything from mixing to mix basic colors red, blue and yellow or red and green.
secondary colors - a green, blue and red.Green is obtained by mixing yellow with a greenish-blue.Purple and blue give the Blue.A mixing magenta with yellow, red color can be obtained.
In theory, the question of how to get the black color of the paint is achieved by mixing the three primary colors in their perfect colors.This cyan, magenta and yellow.However, almost get the perfect black by combining other chromatic colors impossible.The printing and painting using natural black color.
natural black
Black - it is actually the absence of color.The more light rays absorbed by the surface of the object, so it appears dark.In nature, there is absolutely black, but most black carbon Vantablack as close to one hundred percent light absorption, it reflects all the rays of 0.035%.
main natural pigments, which is made of black ink is carbon.Among them, the main - a graphite and carbon black.Artists at the dawn of painting thought about what colors should be mixed to get a black color, and concluded that the mixing black ink is not achieved.During the high Renaissance painters mined black color of burnt bones.It was the darkest shade of matt, available in the Renaissance.
