Sky is Lt blue, fire is firey, so since its blue Id say its the Laser Water parallel....galaxy is kinda rainbowish, and earth looks like looking at a picture of earth through a kaleidoscope (blue/browns/green) or looking at earth from space while hammered drunk running on a treadmill??? (lol not Leafs description of the crystal parallel but mine either way earth looks dirty)
And no its unnecessary, as I used to joke about someone coming out with Pink Sparkle Unicorn Refractors.....just missing the unicorn part
