send to events in sequence

[tycera]

Is there an easy way to pass particles from one event to some other events in sequence or based on probability? 

Simple example .. a particle is blue then it passes to one of three other events that will turn it red, yellow or green.
Can I make it go red->yellow->green->red->yellow->green in order? Or alternatively, can I set a probability for each of the red, yellow green sends?

Apologies if I'm missing something obvious.
