pack colors, the 3.1 rule question

I added the rule sometime in the last week. Older packs are grandfathered in and do not need to change their colors; we would have notified them if they needed to. It was not consistently enforced in the past, which is my fault!

3.0 is the new standard because it's really, really hard to read lower numbers. I know it does inhibit the color range a bit, but I promise I'm not doing it to stomp on fun. I just want everybody (including myself) to be able to read everything on the board.
