-Is it possible to 
    choose the color of the canditats 
    (the square of color 
    beside there names).
    Or to bypass this 
    option?
It is not possible to change the color.  You might want to 
suggest how that would work if you want it;  we thought about it a while 
back and didn't come to any conclusions.  Could you imagine assigning 
colors in a 1000 candidate election?
 
You can disable the pie charts of course if you don't like the 
pretty colors.  We are aware of the party-affiliation color 
thing.
