Value is a measure of where a particular color lies along the lightness–darkness axis. A color's value is its amplitude. Amplitude is the magnitude of change in the oscillating variable with each Oscillation, within an oscillating system Various color models have an explicit term which places the color on a scale from utter black to pure white. A color model is an abstract mathematical model describing the way Colors can be represented as Tuples of numbers typically as three or four values or color components Black is the Color of objects that do not emit or Reflect Light in any part of the Visible spectrum; they absorb all such frequencies of White is a Color, the perception which is evoked by Light that stimulates all three types of color sensitive Cone cells in the Human eye The HSV color model and Munsell color model have an explicit value, while the HSL color model uses a related parameter called lightness instead. HSL and HSV are two related representations of points in an RGB color space, which attempt to describe perceptual color relationships more accurately than In Colorimetry, the Munsell color system is a Color space that specifies Colors based on three color dimensions Hue, value ( lightness HSL and HSV are two related representations of points in an RGB color space, which attempt to describe perceptual color relationships more accurately than
In the HSV and Munsell color models, a color with a low value is nearly black, while one with a high value is the pure color.
The image shows three hues in the Munsell color model. Hue is one of the main properties of a Color described with names such as " Red " " Yellow " etc Each color differs in value from top to bottom in equal perception steps. The right column undergoes a dramatic change in perceived color.
In subtractive color, i. A subtractive color model explains the mixing of Paints Dyes Inks and natural colorants to create a range of Colors where each such color e. paints, value changes can be achieved by adding black or white to the color. However, this also reduces saturation.
Chiaroscuro and Tenebrism both take advantage of dramatic contrasts of value to heighten drama in art. Chiaroscuro ( Italian for light-dark) is a term in Art for a contrast between light and dark Tenebrism, from the Italian tenebroso ("murky" (also called dramatic illumination is a style of Painting using violent contrasts of Light Artists may also employ shading, subtle manipulation of value. Shading refers to depicting depth in 3D models or illustrations by varying levels of Darkness.
