Green is Boss and Superweapon, isn't it?
Well, if it's Granger's as well then I can't be blamed, because I never play as Granger, but I remember SW's because she has the cheaper particle cannon.
Blue is the original Particle cannon and Purple-Blue is the Laser Cannon (Townes).
It's is an interesting idea, but you have to remember that some colours may not be appropriate for it, especially darker colours.
I wonder what a White Particle cannon will look like. Black lasers are invisible
