Below is a list of RAL Classic colours [1] from the RAL colour standard. Alongside every colour, the corresponding values are given for: hexadecimal triplet for the sRGB colour space, approximating the given RAL colour; sRGB value; Grey value calculated from (0.2126 × red) + (0.7152 × green) + (0.0722 × blue) [11] CIE L*a*b* values
The ColorChecker Classic chart is a rectangular card measuring about 11 by 8.25 inches (27.9 by 21.0 cm), or in its original incarnation about 13 by 9 inches (33 by 23 cm), an aspect ratio approximately the same as that of 35 mm film. [5]

A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary color system with no connection to any globally understood system of ...

The Golden State Warriors lost their NBA Cup game against the Denver Nuggets 119-115 on Tuesday night, and head coach Steve Kerr was not happy with the way it ended.
Color quality scale (CQS) is a color rendering score – a quantitative measure of the ability of a light source to reproduce colors of illuminated objects. Developed by researchers at NIST [ 1 ] the metric aims to overcome some of the issues inherent in the widely used color rendering index (CIE Ra, 1974).
