Are the DJI FPV drone propellers foolproof?

The DJI FPV drone propellers are not foolproof. When mounting the propellers, match the propellers and the motor propeller base marked with the same colour: For example, "A" propellers with red marks should be mounted onto "A" motor propeller mounts with red arcs on the outer ring. "B" propellers without marks should be mounted onto the "B" motor propeller mounts that don't have red arcs.
