You should ignore the color till 48 hours after you add CYA. If it is still around at that point, then worry about it. The chlorine levels used during a conversion are extreme and can cause temporary reactions that will go away when the conversion is complete.
If I am reading correctly, you lost 5 or 6 ppm of FC overnight, which means you are heading into the final phase of the conversion. You are still losing FC overnight, and the CC level is probably very high, but chlorine is no longer disappearing as quickly as you can add it. At this point it is most efficient to switch to only adding chlorine in the evenings, or at the very least, only when there isn't direct sunlight on the pool. Sunlight can consume a lot of chlorine during the day.
From what I have seen, things are going very well. You still have a couple of days left, but the amount of effort required goes down at this point, and it is nice to have clear water (even if it is green).
