I don't see it as the USBC designing a stock three patterns and everyone having to use them. I think it's a system of categorizing what each house uses based on ratios, length and volume. All the PBA patterns will go under the "Blue" category, for example. There won't be one catch-all "Blue" pattern for the hard stuff.
In other words, I don't see the USBC dictating to your local house what Red or White pattern they'll use for league. They'll ask for the pattern in tape form and then tell you what kind of pattern you lay down. Some places still don't have the machine technology to lay down complex patterns.
