What is happening is that the color command should take in a name like “color yellow, i. 1" or a CMYK color vector. When you are saying “color 1” it is just starting at the first index of CMYK which is black.

There is a command for your problem though. Just say util.color_chains() and it will color all individual chains a different color.
 
Thanks Jordon for the reply. 

I tried using util.color_chains(). It colors differently upto chain no. 26. After 26 all the chains are of same color, as I donot have chain no after that.
Some utility which can color by residue number would be very useful.
