%  The format of the QueryColorname method is:
%
%      MagickBooleanType QueryColorname(const Image *image,
%        const PixelInfo *color,const ComplianceType compliance,char *name,
%        ExceptionInfo *exception)
%
%  A description of each parameter follows.
%
%    o image: the image. (not used! - color gets settings from GetPixelInfo()
%
%    o color: the color intensities.
%
%    o Compliance: Adhere to this color standard: SVG, X11, or XPM.
%
%    o name: Return the color name or hex value.
%
%    o exception: return any errors or warnings in this structure.
