#pragma ColorManager

/* The ColorManger is used in conjunction with the module Graphics.  Use
   there routines in lieu of Graphics.OpenColor, SetColor, and GetColor.
   The manager keeps a table of all colors requested from it and will use
   this table to distribute new requests of the same hues.  If the exact
   color cannot be found in the table and no more color may be allocated
   the manager will find the closest color in the table to the one requested
   and return that tag.  The tags returned by the manager are completely
   compatible with the color tags used in Graphics. */

/* Find color in table and return tag to it. */

void DeallocColor (unsigned int &tag);
/* Tell manager that the tag is no longer being used. */

unsigned int ColorName (char name[]);
/* Returns the tag of a named color.
