The 2100 mixes all its light grays from Light Cyan, Light Magenta, and 
Yellow, and yes, they can show pink or green edges as you change light sources...

But even a dead neutral printed with color inks will change with light 
source. An Epson 2400 would print these same tones with light gray ink as the main
