The concept of a color system with a hue was explored as early as 1830 with Philipp Otto Runge's color sphere. The Munsell color system from the 1930s was a great step forward, as it was realized that perceptual uniformity means the color space can no longer be a sphere. As a convention, the hue for red is set to 0° for most color spaces with ...
When lightening a color this hue shift can be corrected with the addition of a small amount of an adjacent color to bring the hue of the mixture back in line with the parent color (e.g. adding a small amount of orange to a mixture of red and white will correct the tendency of this mixture to shift slightly towards the blue end of the spectrum).
A color is fully specified by listing the three numbers for hue, value, and chroma in that order. For instance, a purple of medium lightness and fairly saturated would be 5P 5/10 with 5P meaning the color in the middle of the purple hue band, 5/ meaning medium value (lightness), and a chroma of 10 (see swatch).
Philips Hue is a line of color-changing LED lamps and white bulbs which can be controlled wirelessly. The Philips Hue line of bulbs was the first smart bulb of its kind on the market. [ 3 ] The lamps are currently created and manufactured by Signify N.V. , formerly the Philips Lighting division of Royal Philips N.V. [ 1 ] [ 4 ]
NEW YORK (AP) — "I think it pisses God off if you walk by the color purple in a field somewhere and don’t notice it,” Shug tells Celie in Alice Walker's “The Color Purple.”
Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, [1] or excitation purity. [2] [3] This number of parameters follows from trichromacy of vision of most humans, which is assumed by most models in color science.
HSL stands for hue, saturation, and lightness, and is often also called HLS. HSV stands for hue, saturation, and value, and is also often called HSB (B for brightness). A third model, common in computer vision applications, is HSI, for hue, saturation, and intensity. However, while typically consistent, these definitions are not standardized ...
Other sources indicate that it has always been a somewhat redundant phrase meaning an outcry and cry, though such "redundancy" is a feature of the legal doublet. "Hue" appears to come from the Old French huer, which means "to shout", and "cry" from Old French crier ("to cry"). [4] [5] [6] [7]
