public ColorList Colors {get; set;}
Remarks
Most Color properties in TeeChart component, accept the clTeeColor constant value. That is equal to Delphi clScrollBar (or -1, in numeric).
It is a very important feature to have clTeeColor:
When adding new points to a Chart Series, specifying clTeeColor as the point color, it will make TeeChart assign a different color to each point. (See TChart Series.ColorEach property for more information).
When attaching new series to any Chart, having the TChart Series.SerieColor property to clTeeColor will make TeeChart assign a different color to each Series.
Some Series types allow clTeeColor in their Pen and Brushes properties, thus forcing the use of the actual point color instead of the Pen or Brush assigned color.
