You need to be careful giving colours to particles, because the red ones 
will go faster than the blue ones and this affects the simulation :-P

Jokes aside, the colour you use to visualize different copper atoms when 
looking at a structure or trajectory depends on your visualization 
software and you should look at its documentation for help, not here. 
We're busy people and don't appreciate our time being requested for 
something that's probably in the tutorial material for some piece of 
software that you haven't even given us the name of... I recommend VMD
