- * DESCRIPTION
- * The XcmsLookupColor function finds the color specification

- * RETURNS
- * This function returns both the color specification found in the
- * database (db specification) and the color specification for the
- * color displayable by the specified screen (screen
- * specification). The calling routine sets the format for these
- * returned specifications in the XcmsColor format component.
- * If XcmsUndefinedFormat, the specification is returned in the
- * format used to store the color in the database.
