Class Description

*-*-*-*-*-*-*-*-*-*-*-*-* C O L O R class *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                      =================
  At initialisation time, a table of colors is generated when
  the first Canvas constructor is called.
  This linked list can be accessed from the ROOT object
      (see TROOT::GetListOfColors).
  When a color is defined, two "companion" colors are also defined:
    - the dark version (color_index + 100)
    - the bright version (color_index + 150)
 The dark and bright color are used to give 3-D effects when drawing
 various boxes (see TWbox, TPave, TPaveText, TPaveLabel,etc).

  This is the list of currently supported basic colors.
  (here dark and bright colors are not shown).
