FairyCrystal, thank you so much for your very enlightening post, which I just now found sort of late. A lot late, actually. I wish there was a notification of response on a thread so we would know where the conversation is taking place.

I had a similar experience. They got really upset. And yes, incense seems in small amounts seems to be more subtle, but effective.

In my area, stores generally do not carry powdered black food coloring and in the last few years, they don't seem to carry the liquid food coloring. If somebody wants to make black food coloring, mix equal measures of Green, Blue and Red. If the color is a little on the Green side, add a little bit more red.

I actually had a bash at making some black salt earlier on this year and placed it outside of my home and boundaries.

I have so much of it!
I use it in most of my Indian dishes. I love it.
If you have ever bought Chat Masala - it's the main ingredient,
so you may have tasted it, but didn't know what it was, BJ

Chop sweetened onions and diced tomatoes ---add black salt and, Voila, you
have a great simple chutney.
