I'll be testing for this.  I suspect the black is already a mix of colors, and it's biased to blue.  The black only tests are moving to higher Lab A values.  So, my addition of magenta, if I'm really lucky, will *just* offset that.  We'll see.  (While my tests are not the equal of Aardenburg Imaging, I was able to detect most of what we're now seeing in the more sophisticated tests.)
