Question, has this ever happened to you?

I have been making grape wine for many years. I have made wine for grapes, wine kits, and vineyard produced juices. I just started a Chardonay and a Pinot Grigio from 6 gallon buckets of California juice. After I allowed the juice to warm (they were quite cold from refrigeration) I checked the spec gravity, added bentonite, and pitched the yeast (Lalvin D47). The juices were both similar in color to apple juice. Once fermentation started the Pinot Grigio has taken a pink tone, like pink lemonade. This has never happened to me before. Both are in full boil on day two of fermentation and everything appears normal except the color transformation. Has anyone else ever had the occur?

I have had some whites that do look a little pinkish during fermentation, but only a very slight hue. Once fermentation ends, and the yeast settles out, you should be fine.
