Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. [1] In other words, brightness is the perception elicited by the luminance of a visual target.
Here, the chroma color appearance parameter might (depending on the color appearance model) be intertwined with e.g. the physical brightness of the illumination or the characteristics of the emitting/reflecting surface, which is more sensible psychovisually.
A color term (or color name) is a word or phrase that refers to a specific color. The color term may refer to human perception of that color (which is affected by visual context) which is usually defined according to the Munsell color system , or to an underlying physical property (such as a specific wavelength of visible light ).
The HSV (hue, saturation, value) color space values, also known as HSB (hue, saturation, brightness), and the hex triplets (for HTML web colors) are also given in the following table. Some environments (like Microsoft Excel ) reverse the order of bytes in hex color values (i.e. to "BGR").
Some color spaces separate the three dimensions of color into one luminance dimension and a pair of chromaticity dimensions. For example, the white point of an sRGB display is an x , y chromaticity of (0.3127, 0.3290), where x and y coordinates are used in the xyY space.
But for us it was simple: the color of the sky, the color of the heavens, what lies in front of us.” If 1999 was about embracing the unknown and engaging some blue-sky thinking, Pantone ...
In other words, the object can look lighter or darker depending on what is around it. In addition, the brightness can also appear different depending on the color of the object. For example, an object of a grayer color than the exact same object, but this time in a less gray color, will look darker, even when both are just as bright. [3]
In 2009, the National Institute of Standards and Technology (NIST) issued a scientific paper stating that in addition to the typical white light brightness rating of display devices, there was a need for providing "an equivalent measurement that will better describe a projector's color performance when rendering full color imagery".
