I know blue is the default disk color for the disk in the tribes series, and I know that almost everyone gets a different disk, (in the launcher) tail, (disk in the air, the streak) and explosion later on.
The graphic artists could make several popular colors (blue, red, black, white, pink, etc) available in the menu, so you can have whatever color disk you want, with matching tail and explosion.
Even better, when I change my disk to red, or you change it to black, it shows up that way in game, so when I shoot my disk, everyone will see my red tail, and I'll see everyone else's blue (or other color) tail. (like jedi knight 2, where you could see other ppl's lightsaber colors)
