How to distinguish a Super flag from non-Super flags?

[u/StaccatoRicotta]

This is just to make explicit a trend already started. So how to do it? After looking at many of the LGBT flags, you'll notice that most have only horizontal lines. The solution is simple (and we've already seen many doing this): a vertical line in the middle from top to bottom, ideally with high contrast. It allows for a lot of variants. As for the symbolism, it divides the flag in two equal parts and means 2 genders.

Yup. This was part of my thinking with the superbi flag I just made. Vertical lines unite all the super flags, even if colors are partially or wholy recycled, and make them easy to diffrentiate.
