2665% QueryColorname() returns a named color for the given color intensity.
2666% If an exact match is not found, a hex value is returned instead. For
2667% example an intensity of rgb:(0,0,0) returns black whereas rgb:(223,223,223)
2668% returns #dfdfdf.

2670% UPDATE: the 'image' argument is no longer needed as all information should
