What is the best natural acidic stains that can be used in tissue staining (except eosin and chromotrope) ?

Curcuminoids make excellent acidic stains. They are easily extracted from turmeric with 70% ethanol. I usually do a 10-15% (w/v) solution. Spin it down, pour off, and filter the supernatant.
