The new Uize.Color.xCmyk module extends the Uize.Color object by adding a profile for the CMYK color space, and by providing encodings for this color space.

The Uize.Color.colorSpaces.CMYK property - defined in the new Uize.Color.xCmyk extension - provides a profile for the CMYK (Cyan, Magenta, Yellow, Key) color space. The CMYK color model is a subtractive color model used to describe the printing process. Some examples of CMYK formatted colors can be viewed at http://www.december.com/html/spec/colorcmyk.html.

The Uize.Color.xCmyk module defines the following color encodings...

	CMYK array - Colors are encoded as an array, containing four elements for cyan, magenta, yellow, and key components of the color, whose values may be floating point numbers in the range of 0 to 100 (e.g. the color chartreuse is encoded as [50,0,100,0]).
	CMYK object - Colors are encoded as an object, containing cyan, magenta, yellow, and key properties, whose values may be floating point numbers in the range of 0 to 100 (e.g. the color chartreuse is encoded as {cyan:50,magenta:0,yellow:100,key:0}).
	CMYK string - Colors are encoded as a Cmyk(...) formatted 4-tuple string (e.g. the color chartreuse is encoded as 'cmyk(50%,0%,100%,0%)').

Because the Uize.Color.xCmyk module extends the Uize.Color object, and because the Uize.Color object is used by the Uize.Fx module in resolving color values when performing effects, loading the Uize.Color.xCmyk module will allow code to specify colors in the CMYK color space when using the methods of the Uize.Fx module.
