Digital BW, The Print

I went to www.inkjetmall.com and is it safe to assume that the thing 
to buy would be the  
("Piezography Neutral K7 inks for Epson Stylus 2400 -Set of 8 
cartridges")
To me it's not 100% clear but it seems like this so called K7 kit 
includes 8 cartriges but none of them are color cartriges but are 
designed for a specific slot on the Epson R2400.  For example, there 
is a neutral grey ink designed for the yellow postion.  is that 
right?
