I see his points, but I still favor my mapping:
Cyan = Green
Orange = Red
Purple = Blue
Clear = Yellow
What do you think?
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
Clear - Ice Traders! Change color.
YMMV. But this is how I would approach it.
