Sorry, that's not how it works.  When you have 2 files, it's not 1 
for black and 1 for gray.  Actually, 2 bitplanes produces 4 colors, 3 
bitplanes produces 8 colors (not 4), 4 could produce 16, and so on.  

When the first one is showing, the 1's are black and the 0's are 
white.  The same thing happens when the second one is showing.  Since 
the first shows for twice as long as the second, it produces a darker 
gray color than the first where there is a 1 on the first and a 0 on 
the second.  I'd give an example, but there have already been several 
given on this list.
