pack colors, the 3.1 rule question

i understand the necessity of making things here readable but i ALSO think it's always going to be a problem to require colors that are this high contrast because it 1) really limits your options and may discourage people from going in for pack concepts since colors will by necessity fit into a small range that can be similar to others' and 2) what is high contrast on light mode isn't necessarily going to be high contrast on dark mode.

i know the saints' original color was identified as a problem after we formed, and the color we had suggested to us as a replacement was a ~2.2 on the contrast scale. maybe as cyprin suggested something around 2.2-2.5 would be an acceptable compromise? i'm also quite sure a lot of current packs don't fit those requirements so if we were going to do this for visibility reasons it would only make sense to revise all current colors to follow the rules, which is where i think the restricted colors problem would be particularly noticeable.
