The Hibiscus tea I use turns blue when I steep it at my mom's place, but not at mine. I have a very good water filter, she does not. First time it happened, I was quite startled. She had a filter at her place she never used, so we tried it. Yep, filtered water resulted in pinkish tea.
What's in the water is unclear, but there was a lingering unease related to it.
