Dojo generate colors

The one that I want is in

dojox.color.Generator.monochromatic ({ base:myColor, num:6 })
http://bugs.dojotoolkit.org/browser/dojox/trunk/color/Generator.js?rev=14628

This monochromatic function does NOT do what I want
dojo.require("dojox.color.Palette");
var colors = dojox.color.Palette.generators.monochromatic ({ base:myColor, num:6 });
