This category groups different manners of defining a one-dimensional RGBA color gradient.
      
                          The most general way of creating color gradients is to use a 
                    Keyframe Function

                    , but, in most cases, specialized
      gradients such as 
                    Bitone
                    Define a gradient with two colors

                     or 
                    Tritone
                    Define a gradient with three colors
