In my situation, the color is purple right after adding R11L, like it is in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RANwktWJLqU.html. It doesn't start from reddish pink at all. And it actually took about a similar number of R12 drops for it to turn blue whether or not I added 5 drops of R12 before adding R10. So is my problem different than what you are talking about?
