Must have been a fun meeting where all the Alpha Quadrant races sat down to argue what colour the transporter and phasers would be for each species.
"I'm having red phasers!"
"No, I'm having red phasers! You can have a purple & yellow transporter beam with sparkles!"
The Cardassians must have turned up late that's why they originally ended up with Pink phasers!
Haha. I guess part of the original peace treaty with the Federation was Cardassia got to use yellow phasers.
And wold explain why the Klingons and Romulans are "blood enemies" since they both use green phasers!
