The integral quantity “Color fluctuation” computes the variation of color in the case of thickness fluctuations of a layer stack. Up to now the size of the “Color cloud” is computed using distances in L*, a*, b* space. You have now the additional option to compute the distance in the a*,b* plane only, neglecting fluctuations for L*.

In addition, we have removed a bug in the computation: Be aware that the values computed with the new version are different from the ones calculated with previous versions – sorry!
