HYB: pigments - Stunning


STUNNING is always eyecatching here - white ground with bright red fall
spot.

hot water extraction - typical purple
isopropyl alcohol extraction - gorgeous blue shade
safflower oil extraction - slight amount of yellow

This is the first time I've gotten blue - could this be pallida blue
(delphinadin?).  All the blue flowers I've tried so far (not many) have
yielded purple extract.

I've gone back to safflower oil - much faster separation than paraffin
oil/isopropyl combination,  I can pour it down the sink when I'm done,
plus less worry of burning the house down when it spills.
