The high school (NFHS) rule reads the same as ASA, but I haven't found an exact interpretation that's the same. That could take some digging. Absent that, I would have to take the rule as it's written, verbatim.
So, again, where is the colored base located? Entirely in foul ground. If a throw pulls you to that base, then it has pulled you into foul ground!
The interpretation by our state during their tournament was that on a high throw from fair territory that causes the defender to jump upwards, with her entire body still in fair territory except for the one foot that kicks out to the colored base, then she has NOT been pulled into foul ground and must use the white base to get the out. It makes sense to me. If I read the rule verbatim, I don't agree that you have been pulled into foul ground just because you stick one foot into foul ground.
