The Influence of Hue, Lightness, and Saturation on Apparent

WebbLight of any given combination of hue and saturation can have a variable brightness (also called intensity, lightness, or value), which depends on the total amount of light energy present. Lightness of a color is changed by varying the intensity of all three primary colors by the same amount. Webb26 juli 1999 · Saturation (also known as chroma or tone) refers to relative purity.

When beams of light of different colours, such as red and yellow, are projected together onto a white surface in equal amounts, the resulting perception of the eye signals a single colour (in this case, orange) to the brain, a signal that may be …

WebbUsing only the Hue component makes the algorithm less sensitive (if not invariant) to lighting variations. Another popular option is LAB color space, where the AB channels represent the color and euclidean distances in AB space better match the human perception of color. WebbFigure 4.2.1 Lightness, Hue, and Saturation. Color is produced when light is either reflected off of (e.g., a car; a printed map) or emitted by (e.g., a computer screen) an object. Hue refers to the wavelength of that light, from longest (oranges and reds), to shortest (blues and violets). Figure 4.2.2 shows nine swatches of color with ...

Webbcolor properties: hue & saturation Color has two unique components that set it apart from achromatic light: hue and saturation. Visually describing a color based on each of these terms can be highly subjective, however each can be more objectively illustrated by inspecting the light's color spectrum.

WebbIt is argued that the effects of brightness and saturation on perceived distance from the observer can be attributed to figure–ground differentiation between adjacent regions in the visual field; but this argument does not cover the effect of hue under achromatic background conditions.
