Of course you can name these toxic vegetable dyes?

Not off hand. However, the most common red dye (vegetable) from about
30 years ago was removed from the market due to toxicity.

That dye, red dye No. 2, is also called amaranth,
but it is not a vegetable dye. It is a synthetic
dye made from petroleum or coal tar.
