Grey Rainbow (Energy)

Grey Rainbow Energy is an iconic energy used by most Caytite-Tacnytes that was modified from the origonal diagram of Rainbow Energy by Tac Nayn. The main appearance of projected grey rainbow energy is simply a straight or curved greyscale rainbow. It is one of the more controversial energy sources since it is only able to efficiently provide thrust and oxygen in Dark Space. Attempting to use it in reality usually causes the user to pass out or knock into something. All Caytite-Tacnytes are naturally born with Grey Rainbow Energy at their disposal.

Origin
Nyan Cat was the first to come up with the idea of Rainbow Energy before any Caytites were able to take to space. When he teamed up with his brother, Tac Nayn, they argued over whether it should have colors or greyscale until they separated into their own projects.

Nyan Cat made a full-quality and authentic Rainbow Energy source that looked exactly like a Rainbow, while Tac Nayn made a greyscale Rainbow that worked only under travel through Dark Space. Tac Nayn discovered Dark Space when he accidentaly got pulled into a black hole while he was infusing himself with the Grey Rainbow energy and found that it was impossible to fly through it without the use of Grey Rainbow energy.

Nyan Cat's discovery of infusable Rainbow Energy (and Tac Nayn's discovery of possible travel through Dark Space) created a huge surge of advancement in the Caytites and they were the first to touch the stars.
