% QueryMagickColorname() returns a named color for the given color intensity.
% If an exact match is not found, a hex value is returned instead. For
% example an intensity of rgb:(0,0,0) returns black whereas rgb:(223,223,223)
% returns #dfdfdf.
%
% The format of the QueryMagickColorname method is:
%
% MagickBooleanType QueryMagickColorname(const Image *image,
% const PixelPacket *color,const ComplianceType compliance,char *name,
% ExceptionInfo *exception)
%
% A description of each parameter follows.
%
% o image: the image.
%
% 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.
