- Based on the overall color of the dragon, especially the design and color of the head, it has been determined that the dragon shown is in fact "Rainbow Dark Dragon".
- Given this, if taken realistically, this card's name and artwork is a half-truth. Because rainbows are a source of light (namely the sun's rays being refracted into different wavelengths) almost no forms of gravity affect them as they are the fastest thing known to man. However, the said dragon in this card's artwork may be a nod to the only thing that light can't escape, which is the gravitational pull of a black hole.
- This card's name may be a reference to the novel "Gravity's Rainbow" by Thomas Pynchon.
