Thanks Roy. That's helpful.

What's not clear to me is 'what is warm tone', 'what is cool tone',  
etc, and how the mixes work. I normally use Epson Enhanced Matte (or  
Heavyweight Matte, or Archival Matte ... they seem to rename this  
paper every other week ;-). I see choices for sepia, neutral and  
carbon. I have a test print of a grayscale step wedge, printed 7  
times with 7 different mixes of the three so I can see the color  
tones, and all but one of them looks virtually identical except for  
carbon-1, neutral-1, 85-15 mix. The inverse, neutral-1, carbon-1,  
15-85 mix, doesn't look anything like it.

Is there some guide with approximate color swatches that I can work  
from? This gets expensive in terms of time and ink consumption. The  
tutorial doesn't seem to have anything like that, nor do the various  
read-me files. Perhaps on the web somewhere?
