RGBto
Converts the components of a color, as specified by the default RGB model, to an equivalent set of values for hue, saturation, and brightness that are the three components of the HSB model.
If the out argument is null, then a new array is allocated to return the result. Otherwise, the method returns the array out, with the values put into that array.
