HCL (Hue-Chroma-Luminance) or LCh refers to any of the many cylindrical color space models that are designed to accord with human perception of color with the three parameters. Lch has been adopted by information visualization practitioners to present data without the bias implicit in using varying saturation .
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 .
The Munsell color system, showing: a circle of hues at value 5 chroma 6; the neutral values from 0 to 10; and the chromas of purple-blue (5PB) at value 5. In colorimetry , the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value ( lightness ), and chroma (color intensity).
The IPT color appearance model excels at providing a formulation for hue where a constant hue value equals a constant perceived hue independent of the values of lightness and chroma (which is the general ideal for any color appearance model, but hard to achieve). It is therefore well-suited for gamut mapping implementations.
Therefore, the value z can be deduced by knowing x and y, and consequently the latter two values are sufficient for describing the chromaticity of any color. The derived color space specified by x , y , and Y is known as the CIE xyY color space and is widely used to specify colors in practice.
Got it home and saw it had the name of American artist Charles Aysocki. I paid $60 and I think its value is much higher. Image credits: Is that Wired or Wonderful thing
Hims compiled a list of the top 25 U.S. counties for dating based on the number of single households, median age, restaurant volume per capita, and proximity to a major metropolitan area.
This system stores a luma value roughly analogous to (and sometimes incorrectly identified as) [9] [10] luminance, along with two chroma values as approximate representations of the relative amounts of blue and red in the color.
