  2. Color difference - Wikipedia

    en.wikipedia.org/wiki/Color_difference

    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 ]

    A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
