 **getSelectionBarColor** - _Function(value) or Function(minVal, maxVal) (defaults to null)_: Function that returns the current color of the selection bar. *If your color won't changed, don't use this option but set it through CSS.* 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.
 
+**getTickColor** - _Function(value) (defaults to null)_: Function that returns the color of a tick. showTicks must be enabled.

 **getPointerColor** - _Function(value, pointerType) (defaults to null)_: Function that returns the current color of a pointer. *If your color won't changed, don't use this option but set it through CSS.* 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. To handle range slider pointers independently, you should evaluate pointerType within the given function where "min" stands for `rzScopeModel` and "max" for `rzScopeHigh` values.
 
 **hidePointerLabels** - _Boolean (defaults to false)_: Set to true to hide pointer labels
