Question: Plot points in CIE 1976 color space

I want to plot some color points in CIE 1976 color space with SpatterPlot command exactly as showed on the help page. When I try:

restart:with(ColorTools):with(ImageTools):
barvy:=Color("Lab",[80.38,13.50,7.96]); 	
SpatterPlot(barvy,symbol="box");

I got the error:

Error, invalid input: ColorTools:-SpatterPlot expects its 1st argument, colors, to be of type list({ColorTools:-Color, name, string, list({float, nonnegint}), specfunc({COLOR, COLOUR})}), but received _m2194815429568

Where is the problem?
