How can I plot XYZ-Color surface?

I want to plot a function with 3 variables : f(X,Y,Z) And, the value of function will be represented as color. But, how can I plot this function? What matlab code or function I have to use?

[Alexandra Harkai]

Would you expect the whole 3d domain to be coloured in?

[Massimo Zanetti]

The graph of a scalar function of 3 variables lives in 4D space. One way to visualize it can be using volumetric plots (representing 4th dimension as color intensity)

This is ambiguous. Are X, Y, and Z the CIE color space images (see this link, or are they spatial cartesian coordinates? It makes a big difference.
