I thought it was really interesting that we don't just see from one part of 
the brain (like the visual cortex) but from many. I actually never knew 
that.  I think the readings said like 36 areas are affected by our vision. 
Wow, that's alot!
In the next readings, on color, I enjoyed the part that talked about why 
sometimes it's hard to distinguish between black and navy.  This is my 
problem sometimes, you see a car and you think, that's black, no wait maybe 
it's dark navy.  It seems like it would be an easy task to differentiate 
between two colors but apparently it's not that easy.  The readings said 
that sometimes it's hard to choose which it is, black or navy because one 
reason could be that the reflectance of the blue is low (the lightness of 
the color makes it hard to detect the color).  Also, the color can be too 
dark, which is when the mix up occurs (is it black or navy)
I also think that it's really neat that when you look at a something blue 
for a while (stare at it) and then look to a white piece of paper, you will 
see the opposite color, Yellow.  How does this happen? I still don't 
understand why.  It is a little confusing because it is the complete 
opposite of blue so why do you not see blue?  Anyone know?
