Looking into the color2D.matplot code showsthat this is by design. You 
might want to contact the package maintainer and send suggestions how to 
patch the function (or better, send the patch itself) in order to show 
appropriate labels.

Of course, for a worksround, disable axes

     show.values=TRUE, axes=FALSE)

and add manually constructed axes by the axis() function later on.
