The intensity of color is a term that defines the photometry flow amount of light passing through a lighting source. A unit that establishes among other things the purity and quality of the color in an image with a certain resolution. The intensity of color when combined with the other characteristics of an image defines the color contrast. Let's see below a series of applications in which the intensity of a color.
In the International System of Units it is denoted as Candela (Cd) and is defined as "the intensity of a monochromatic light source of 540 THz that has a radiant intensity of 1/683 watts per steradian" , and has the following mathematical expression that appears in the image. The saturation of an image is manipulated based on the intensity of the color, if the power of the tone is lacking, the image will turn grayish. Therefore, the higher the saturation, the greater the color intensity.
Today's technology for making displays for computers, telephones and televisions takes color enhancement seriously. First the creation of plasma screens began with the race for a more realistic color intensity, then LCDs gave greater mastery of movement thus maintaining defined colors. Today's LED displays use micro bulbs that fully illuminate the image, providing better image quality with truer colors.
Hair dyes are also a good example of color intensity, the combination of chemicals that they have establishes different tones so that the hair can turn into a diverse range of colors in which the intensity can create various types of black or brown.
