Picker Color Model

  The Picker is the default color model for the color mixer.  It
  contains the following components:

  *   Spectrum option menu

  *   Color spectrum and its title

  *   Color interpolator and its title

  *   Smear button

  *   Undo button

  *   Two paint bucket buttons

  *   Arrow buttons

  The color spectrum is a static collection of colors.

  The spectrum pulldown menu lets you set the spectrum to
  one of the following common color palettes:

  *   ``Rainbow'' spectrum (white, red, orange, yellow, green,
      blue, blue-violet, violet, brown, and black)

  *   Pastels

  *   Vivids

  *   Earthtones

  The four color palettes provide a wide variety of colors for
  you to choose from.  The spectrum option menu also includes
  any palettes specific to an application.

  When you click and release MB1 on a spectrum tile or
  interpolator tile, that color becomes the new color.  The tile
  you click on also becomes highlighted, identifying it as the
  currently selected color.

  You can use the selected color without modification, or you
  can do one or more of the following tasks:

  *   Use the interpolator to blend the selected color into
      various shades.

  *   Use the arrow buttons to make the color lighter or
      darker, warmer or cooler.

  *   Switch to another color model and use the features of that
      model to modify the current selection.

  Use the two paint buckets to load the interpolator with the
  color or colors to blend:

  1.  Click and release MB1 on a spectrum tile or interpolator
      tile.

      The color display box displays the color of that tile.

  2.  Click on a paint bucket, which fills the interpolator end
      tile below it with the selected color.

  3.  Fill both interpolator end tiles or one, in which case the
      color of the empty interpolator end tile defaults to white.

  As an alternative to the paint buckets, you can use the
  eyedropper to load the interpolator.  Clicking and holding
  MB1 on a spectrum or interpolator tile, the original color
  tile, or the new color tile causes the pointer to become an
  eyedropper filled with the color of that tile.

  You can move this eyedropper to the interpolator and use it to
  fill one of the two end tiles by clicking on MB1.  If you do not
  position the eyedropper directly on one of the two end tiles,
  the tile closest to the end is filled with the eyedropper color.
  Note that the cursor must be inside the interpolator.

  Use the undo button to reverse the last interpolator action,
  which can be a smear, the filling of an end tile, or the
  activation of one of the warmth or lightness adjustment
  buttons.
