how to serial.read multiple vars at once [solved]

Hmm how should I use the for-loop?
Because if I send the whole array, how do I know when I got the first, and when the second number?

If I send them just one line after the other, they will be stored in the same variable.

Using a for loop like this, nothing will happen.

//arduino
  if(Serial.available()){
    for(int i = 0; i > 1; i++){
      col[i] = Serial.read();
    }
  }

//processing
  Arduino.write(col[0]);
  Arduino.write(col[1]);

Want I need is some way to say:

  1. byte = red
  2. byte = green
  3. byte = blue
    (1.)4. byte = red
    (2.)5. byte = green
    (3.)6. byte = blue

and all I get is:

  1. byte + 2. byte = red
    no byte for green...

regards

p.s.
I'm familiar with the Serial commands, I just lack the knowledge on how to integrate them into what I want to do.

p.p.s.
I somehow can't find a decent example where a larger amount of data is sent to arduino (which should suffice for gettinge the idea), only vice versa.
