(Sorry for not finding a better title to my question. I'm not shure if 
this has something to do with metaprogramming... I have hear about that, 
but never had time to learn about it, so I don't know what is 
metaprogramming exactly)

Is there a way to do something like this?

arr = [ "red", "green", "yellow" ]


# the following arrays should be incremented with the loop down
@red = []
@green = []
@yellow = []

#here the loop that should increment the arrays
20.times do
   arr.each { |color|
      rand(60)
      unless @color.include?(aleat) #this doesn't work
         @color.push(aleat) # this doesn't work...
      end
   }
end
      ...
      ...


Thanks in advance.
