Mixing in color ink, is mixing in color ink. It will fade the same, no matter 
what head it came out through or what tank it came from. It may simplify the 
printing process for less demanding users, but if you don't like the ramp it 
gives you on a given paper, you are still stuck correcting that with more color 
ink, via a color process... thats why I see the HP "black and gray only" 
printing method as less, not more. I print with it on one fine art paper, and its 
cool in the shadows, but not in the highlights. On another its quite warm 
throughout, but more warm in some areas than others. So I have to neutralize, and 
I can't do that without printing through a mode that allows me to use the 
other inks...
