In a dream, I just got inspiration for what a wedge BUG society would look like. Well, to be specific, it was a dream about Metal Gear Solid involving Snake sneaking into this sort of society (with LPers commenting on it) and I realized the connection to a BUG wedge afterwards.
The scene that happened in the dream (minus Snake and LPers) took place in an area with a lot of homeless people. Then suddenly, there was a march of strange bestial and colorful machines through the area, driving away the homeless people and clearing out the area, including some machines drilling up through the ground. Then, the machines stopped and opened up: they turn out to be vehicles for rich people, who come out in fancy dresses, and in the cleared out area, a dinner party is held with the people dancing to a waltz.
Not all of the following came from the dream, but rather was extrapolated from the events of it and the unspoken knowledge I had of the society from the dream. It is a society where it is believed that the natural state of humans is to be creating machines, not really innovating, but rather creating variations on themes set down by artificers of old, who were revered for their skills. The society believes in predestination. Everyone is born to fulfill a certain role, and whatever role they fall into is the one that they were always supposed to. How they handle that role then determines their reward or punishment in the next life. The ideal is that everyone is given basic education where they are allowed to explore different forms of artifice and then, once they discover the role they are destined to fulfill, they are given further education in that field. In practice, however, the rich take advantage of this system such that only they get access to the proper education and resources. The poor are considered to not be succeeding at their roles and the rich are considered to be succeeding at their roles, and thus are considered blessed and beyond question, so they view themselves as being within their rights to do whatever they want with the poor.
The green part comes from the religious beliefs of the society, the reverence of past artificers, and the bestial nature of the machines they create. The blue part comes from the machines, the fact that knowledge of artifice is considered important, and the way people are given a chance to determine for themselves what they are destined to do with artifacts (in theory). The black part comes from how the rich take advantage of the system and abuse the poor. The lack of white comes from how the society doesn't try to protect everyone, and the lack of red comes from how there is neither empathy among the rich nor rage among the poor.
In terms of card implementation, I think the colorful bestial machines could be a lot of fun, making colored artifact creatures that feel different from those of Esper. You could have art of guys with punchable faces riding on top of a green artifact elephant drinking wine while poor people have to get out of the way. But the real fun comes when red and white inevitably start infiltrating this world, and you get poor people revolting and rich people starting to become sympathetic to their cause.
