Dying Colour on Coral

[riosrios]

Anyone knows which chemical substances are used to dying colour on the soft coral??

I just want to know the answer, but not trying to do so

Thanks a lot

I do not know, but I'd guess it is simply food coloring.

thanks for answering, but any chemical name there?

Well, remember I'm only guessing, but it is what I'd try.

This article lists food coloring dyes and has links to the chemical structures:
