Subtopian Standard

The Subtopian Standard is an informal name given by vexillologists to the common use of green and yellow on Subtopian flags.
While many historians have debated as to why there is a frequency of green and yellow on Subtopian flags, the common consensus is that the popularity of the colors and the spread of the colors within post-immigratory Subtopian culture is due to the strong Islamic presence in Subtopia, of which green is a common cultural color.
Due to no provable common origin of the popularity of the colors, some historians suggest a form of the Convergence Effect, where the popularity of the colors converged from differing origins at the same time, uncoincidentally.
