**getSelectionBarColor** - _Function(value) or Function(minVal, maxVal) (defaults to null)_: Function that returns the current color of the selection bar. If the returned color depends on a model value (either `rzScopeModel`or `'rzSliderHigh`), you should use the argument passed to the function. Indeed, when the function is called, there is no certainty that the model has already been updated.
