CIEDE 2000 is not mathematically continuous. The discontinuity stems from calculating the mean hue Δ H ′ {\textstyle \Delta H^{\prime }} and the hue difference Δ h ′ {\textstyle \Delta h'} . The maximum discontinuity happens when the hues of two sample colors are about 180° apart, and is usually small relative to ΔE (less than 4%). [ 24 ]

ΔE is the fluid's mechanical energy loss, ξ is an empirical loss coefficient, which is dimensionless and has a value between zero and one, 0 ≤ ξ ≤ 1, ρ is the fluid density, v 1 and v 2 are the mean flow velocities before and after the expansion. In case of an abrupt and wide expansion, the loss coefficient is equal to one. [1]
The XYZ primaries will have XYZ coordinates [1,0,0], [0,1,0], and [0,0,1] in XYZ space, so the columns of the inverse matrix above specify the XYZ primaries ( Cr, Cg and Cb) in RGB space. Dividing each column by its sum will give the coordinates of the XYZ primaries in rgb space which yields: Cr = {1.27496, -0.27777, 0.00280576}
Optimal colors (theoretical maximum chroma of surfaces) point cloud in CIE Lab, top view Optimal colors point cloud in CIE Lab, left view The CIE 1976 (L*, a*, b*) color space (CIELAB), showing only colors that fit within the sRGB gamut (and can therefore be displayed on a typical computer display).
To decode an Elias delta-coded integer: Read and count zeros from the stream until you reach the first one. Call this count of zeros L.; Considering the one that was reached to be the first digit of an integer, with a value of 2 L, read the remaining L digits of the integer.
Illuminant E is an equal-energy radiator; it has a constant SPD inside the visible spectrum. It is useful as a theoretical reference; an illuminant that gives equal weight to all wavelengths. It also has equal CIE XYZ tristimulus values, thus its chromaticity coordinates are (x,y)=(1/3,1/3). This is by design; the XYZ color matching functions ...
The Sinclair Executive was the world's first "slimline" pocket calculator, and the first to be produced by Clive Sinclair's company Sinclair Radionics.Introduced in 1972, the calculator was produced in at least two versions with different keyboard markings; a variant called the Sinclair Executive Memory was introduced in 1973.
