ASA has done a good job of covering all of the possible "what if's" in their double first base rules. It does make for one rather long rule, taking up almost an entire page of the rule book! But they do lay out scenarios where the defense may use the colored bag and the offense the white one. For instance, when the throw is coming from foul ground or the fielder at first has the ball and must complete the play from foul territory.
These exceptions to the rule make sense. If the fielder has the ball in foul ground, but we still require her to complete the play by using the white bag, the safety base ain't so safe anymore! Requiring the fielder to use the white bag on this play puts the runner and fielder on a criss-crossing collision course. So, the well-thought out ASA rules make some exceptions in the name of safety.
Unfortunately, not all sanctioning bodies have included such exceptions in their rules. Some still require the runner to use the colored bag, and the defense the white portion, on all plays at first base. No matter the good intentions behind the safety base, without some of these exceptions you just have an accident waiting to happen.
Before making any blanket assumptions that the defense ALWAYS has to use the white bag and the runner ALWAYS has to use the colored one, you really need to read the written rule for your particular association or sanctioning body.
