Go back to the beginning.  It's not what color is what, but what action 
is what.  Our original thinking:

Blue - Originally the game was "Ice Traders" and John thought the blue 
was closest to ice, so they trade color for color.
Green - grow some new pieces.
Red - fire the torpedoes!  Spill blood!  Attack!
Yellow - flames from the thrusters as you move from place to place.

So, with your four colors, I might suggest:
Cyan - blue sky, movement from place to place.
Orange - attack!
Purple - a peaceful color for growing.  Like green, another chlorophyll 
color.
Clear - Ice Traders!  Change color.

YMMV.  But this is how I would approach it.
