Color Tone, Saturation And Lightness. Coloring In Painting.

Color tone is a quality of chromatic color, which we usually name red, orange, yellow, green, etc. It can be compared to one of spectral or purple colors. Color tone is designated by length of the wave expressed in micrometers.

All achromatic and chromatic colors are advanced by one characteristic – lightness, or relative brightness.

Lightness is a relation of a stream of light reflected or dropped by the object, to a falling stream; it is expressed in relative units. From here follows that than more close the color characteristic to unit, that it will be lighter: the darkest places have lightness, close to zero.

The color saturation is a degree of difference of chromatic color from achromatic of the same lightness.

In a chromatics often measure not a saturation perceived visually, and so-called cleanliness, or colorimetric saturation of color, which is advanced by the relation of brightness of a spectral component to the general brightness of color. Color purity – relative size also is usually expressed in percentage. Cleanliness of spectral colors is accepted for unit, or for 100 percent, and cleanliness of achromatic colors is equal to zero.

Knowing color tone, lightness and color saturation, it is possible to measure any color quantitatively. The slightest change of one of three sizes advancing color involves color change.

The method of definition of color under these three characteristics, convenient because it is possible to advance color quantitatively, is successfully applied in various areas of a science and engineering, including in printing industry, textile production, color television, etc. where to color measurement apply special devices – spectrophotometers and colorimeters of various systems. All methods of definition of color in colorimetry are based on comparison of colors, which lie in one plane and are in identical conditions of illumination.

In painting at work from location the artist should analyze and compare the colors inherent difficult under the form in volume objects or subjects, which, as a rule, are in an environment of the color environment or subjects of other color and which are possessed on several, sometimes rather removed from each other, plans and, hence, various conditions of illumination.
