Pink Blue: Gender shift stone

I felt a tugging in my pants coming from the stone. I pulled it out and it flew out of its box into the sparkle. It dropped down on the other side of it. I carefully stepped around it and went to pick up the stone, but it looked different it was a different color, it was pink. I tried to make a test wish for blue tires but it was different. In addition to the need to turn away I felt a shifting in my whole body, and when I could look again I was a girl and the stone was blue.
